The Game Boy version, i.e. good for its time over 20 years ago but the last frickin' version you should get today. Super compromised, and you can get better versions for cheaper just about anywhere. Anywhere.
Huh, I didn't even known Pac-Man came out on the Game Boy. I guess that makes sense though, since it's popular and all.
I wouldn't mind repeats or "outdated" versions of games coming to the Virtual Console if they at least released more than one per update. I appreciate wanting to preserve as many different versions of a game as possible, but when that comes at the expense of an original game that could have been released, I find that annoying.
