I'm playing Devil May Cry 2 right now and it's a pretty horrible game. I'd stop playing it but I want to finish it at least once and be done with it, since I want to play the entire Devil May Cry saga. The graphics are boring and so is the gameplay. The music is lazy and can hardly be heard over the guns. The story? What story? It's just some cutscenes interconnected in between boring easy battles. This game is pretty disappointing, especially after having played Devil May Cry 1 immediately before.
Metal Gear Solid 2 was probably the biggest disappointment but only because it was my most highly anticipated game ever. It ultimately couldn't possibly live up to my lofty expectations. I still like the game, but I was expecting the level of quality that we saw in the tanker intro to be maintained throughout... and I wasn't expecting Raiden to fill in for Snake nor all of the silly, crazy shit that happens in the game.
... I like Metal Gear Solid 4 a lot less, but I have never been able to get overly hyped for a new entry since. At least Snake Eater still managed to surpass my expectations in a big way!
I feel like I'm more likely to revisit 3D Land than I am NSMBU, at least by myself.
I was actually a little disappointed in Wario Land 2 (having just played it for the first time this year). I loved the first Wario Land, even though admittedly, a lot of that is nostalgia. I guess I just was not as much of a fan of Wario's shift to the puzzle platformer. I liked the original's emphasis on secrets, which wasn't unlike Super Mario World in how it handled things. I was also disappointed at how awkward Wario seemed to control in WL2. I didn't like the multiple 'tiers' that every level had, rather than the camera simply scrolling. I know it was a limitation of the time, but it still made for kind of a clunky experience. Wario basically controls exactly the same as he does in the first game, physics and all, but he feels like he moves twice as fast, and I think that's what makes the jerkiness of his controls stand out a lot more.
Advance Wars: Days of Ruin on DS. It did a few things right, but more things wrong.
Lufia on GBA... ug. Not worthy of the name.
Valkyria Chronicles 2 on PSP, definitely a disappointment. Loved the first one.
I'd probably throw in the PSP MGS: Peace Walker game, although I think it is a good game with bad controls, so maybe if it gets ported elsewhere at some point I will change my mind.
Resident Evil 5 on PS3. I don't dislike this game as much as some people, I found it kind of fun to play through with someone else, but as the sequel to the utterly amazing 4? Eh.
I was actually a bit disappointed with Ocarina of Time on N64 at the time. I found it kind of linear with a bland overworld. Yeah. My appreciation for it has grown since then, but it's still one of my least favorite of the console Zelda games.
Hmmm. I'm still a bit surprised by all of the negativity concerning 3D Land. I think it's obvious that the game was a bit rushed and is a little unpolished and lacking as a result, but the core game is still ridiculously fun... easily my favorite handheld exclusive Mario game. I also think that incorporating the 2D powerup system back into the 3D games is the best thing ever.
I'm still hoping that 1up Studio is working on a followup... one that they can spend some time on and add some more interesting ideas to.
For me, Mario Kart Double Dash is definitely one of my biggest disappointments because of the Battle Mode. I had waited a long time for a successor to Mario Kart 64's Battle Mode, in the running for the greatest multiplayer mode of all time, and what Double Dash had in that department was a huge step down. The racing was all well and good but it couldn't take the bad taste out of my mouth.
Yoshi's Story is also pretty high on my list and that's as someone who hadn't played Yoshi's Island (and I still haven't). I imagine that lots of Yoshi's Island fans were really psyched for Yoshi's Story and were blindsided by what it turned out to be.
And Majora's Mask. Ocarina of Time was my most anticipated game ever and it lived up to my expectations and blew them away. Then the sequel came and it was so obtuse and inaccessible that I didn't beat it until many years later on Gamecube. Almost hard to believe.
I also hate to say it, but Radiant Dawn. I wasn't expecting a lot, but there were a lot of things I didn't like about it. It was very obviously a Gamecube game that got moved to Wii, right down to the cropped images during the dialogue scenes. I didn't find myself caring for most of the characters, and the first third of the game was way too difficult. Even towards the end, I had a hard time getting motivated to keep trudging onward. The story lacked that sort of suspense that I thought the first game had. I always felt like I was building to something in the first game, but in the second, everything just felt too truncated.
I'm also glad I got back into Xenoblade. I hit a REAL lull in that game, to the point where I didn't know if I really wanted to get back into it...but I'm glad I did. The game has really picked up since the half way point.
Resident Evil 6. I was expecting shit, and it STILL managed to horrendously disappoint me. No joke, I played the first 30 QTE filled minutes and actually had to shut the game off (This was a week or so ago.) because I found it literally offensively bad what they did to the game. Holy fucking shit, it still gets my blood boiling. Resident Evil 5 was a disappointment, but it still entertained me. This offends all sensibilities of good game design.
Mega Man X3. It's a game I like a lot, but I don't love nearly as much as the first two. It just doesn't feel like it fits with the first two IMO, but I think it's mostly due to a lot of the assy guitars in the game. There are some cool compositions but I think the guitars in the game sound pretty out of tune or something. The gameplay is mostly solid, but I could never figure out how the mechs worked. I think the whole game in general was a little too much to take in. I mostly like my Mega Man games kind of simple. I like some things to find, but I think I had a hard time wrapping my head around some of the things in X3.
Bit.Trip Runner was a pretty big one for me, but I've gone into that before.
Yoshi's Island, too. I've tried multiple times and I always lose interest by the fourth world. I'm willing to try again on the SNES version, since I'm sure it benefits without the GBA's cramped screen space.
Yea, I feel exactly the same way. Don't get me wrong, it was pleasant to play through and I 100%ed it, but it just lacked anything interesting or noteworthy whatsoever to me.
That's how I feel about it. 64 and Sunshine have incredible platforming depth. Galaxies have unrivaled magical splendor. NSMB has multiplayer and a new gimmick in every stage, plus some dastardly hidden star coins. 3D Land has...pointless raccoon tails. Didn't care for the claustrophobic level design and the niggling issues caused by the run button, either. And the post-credits content was a lot of fluff. Really just felt like Nintendo tried to mash 2D and 3D Mario together and lost the best parts of both in the process.
I just recently played DMC2 as well, and I also finished it for the exact same reasons (just to say I did it), but I have to say it's completely skippable in hindsight. DMC3 is such a huge improvement, it's mind-boggling how off the mark DMC2 was.
* Resident Evil 4: This is less about the quality of the game (it's astoundingly good), and more about what could have been (the RE game I always wanted) and the direction that the game steered the series in. Nothing in video games has ever disappointed me more than RE4's final re-design. RE4 marked the end of a series that I really loved, and not only is that series never coming back, it's only getting worse and worse. Speaking of which...
* Resident Evil 5: Four years after RE4, Capcom follows it up with a dumbed-down, uninspired, "safe sequel" that is worse than its predecessor in nearly all respects. Despite the part about it no longer being survival horror, playing RE4 was such an enjoyable experience. And yet the sequel to that game couldn't have been any less interesting than it was.
* Wind Waker: All Zelda games post-N64 have been disappointments to an extent, but Wind Waker fell the furthest short of my expectations than the two follow-up games. It was rushed to release, and it showed.
* Metal Gear Solid 4: I was late to the MGS series other than the first one. Playing them all in order, the excellent game design of 2 and 3 really exposed MGS4, which just couldn't come anywhere near the high level of those games. The game relied too heavily on fan service alone to carry it, and it just didn't work its magic on me.
I'll second Skyward Sword, but only in part. I loved a lot of the game, but I was extremely disappointed by the story, the overworlds, the (lack of) exploration, and the new races/how they played into everything, including their lack of towns or other cultural hubs (except for the Mogmas; they didn't diappoint me, and I thought they were well done, but I do keep forgetting they were even in the game...).
I was a little disappointed with the harp and the lack of items in the game (minus a few upgrades and medals, I knew what every item in the game Link was going to get before I ever played it, and that was just from watching the E3 videos, IIRC), but neither of those were a big deal. I was also very disappointed in the art style. It just didn't look very good to me. Actually, let me clarify: it looked great on the characters (excluding some of the monsters because it made several of them decidedly non-menacing) but I felt it looked horrible on most of the environments (particularly the up-close environments). So, yeah. It's my least favorite art style in the Zelda series to date, truth be told. Oh, and Fi was a disappointment, but that goes without saying.
Okami is another big one for me. I kept hearing all this praise for the game and how it was the Zelda game we deserved, but I just didn't like it. I mean, I liked the first section to some extent but Issun was more annoying than any other Zelda sidekick ever, the combat was clunky (thanks, Wii version), and I didn't really connect with any of the characters on any real level until right before I beat Orochi. And then, I learned that the ultimate Big Bad I had just defeated wasn't the ultimate Big Bad, so I had to travel to a new land with new people and defeat THAT ultimate Big Bad only to learn that there's ANOTHER new land presumably with new people and the REAL ultimate Big Bad that I have to travel to and defeat, and at that point I just put the game down and couldn't bring myself to go back to it. Maybe one day...
Fallout 3 has been another one. I feel like I could eventually learn to get into it, but it's going to take some time. I've really enjoyed Skyrim, and I hear that Fallout 3 is ultimately a post-apocalyptic Elder Scrolls type game, but since I had never played an Elder Scrolls game when I first tried to play Fallout 3, I didn't really understand what I was doing, and I just couldn't get into it.
EDIT: And for what it's worth, I loved 3D Land, especially once the special stages unlocked. It certainly didn't feel rushed or unpolished at all to me.
