To be honest I love a good time sink. I tend to really get absorbed in games, so if I'm playing and I finish it in two sittings, I'm going to feel a little cheated, or at least not as fulfilled as I can be. Games like Fallout 3, Half life 2, any Zelda or Mario game, all great lengthy, well paced games. 10 hours is simply too short for me to spend so much money on full price. Then again I'm a dirt poor student, so value for money is something I thrive on.
Edit: oh to guess the games, I'll go with super mario bros (which has been on about a bajillion consoles) and seeing as you said one was updated I'll guess a street fighter game.
