Oh man! You're missing out. Picross DS is the best. It's like the 3D one, but with a manageable amount of dimensions. (I didn't like the 3D aspect of the 3D one.) Seriously, I restarted Picross DS at LEAST five times, straight through.
I blame Nintendo. I played through all the puzzles on 3D, have done most of the time trials, and still have tons of downloadable puzzles that I haven't done yet. Lots of content.
Fire Emblem looks really good, but it also looks life-consuming, I'd almost rather have a shorter/cheaper game that told a more concise story, but for FE mega-fans who want to play for 100s of hours it looks like an amazing package.
@Zero But it's not an action game, it's an RPG, that's why I was annoyed.
