I kind of miss the days where you could just pop a game into your NES or SNES, play for an hour, then move on to something else.
90% of all games that come out these days, you can't even play if you don't have at least two or three hours to sink into it.
Pretty much the only games that don't fall under this category are games like Mario Kart, Mortal Kombat and MAYBE a few of the FPS games.
I like having dozens of hours of content in a game that I plan on playing for hours on end. I would still be happy with a few more casual-style games that you can pick up and put down without having to fully immerse yourself in it to enjoy it.
