Long games. I don;t have "time" either... but I find time... I'd rather spend $70 and have no time to play 100 hours, then spend $70 bucks ten times and have time... If a game takes 100 hours, it means I don't have to spend money for a long time, and get a long amount of enjoyment out of the game.
Having said this... there is such a thing as TOO LONG! Games like Crysis or DOOM etc need to be shorter, since they are an action based game, and having it too long would just be repetative and annoying. I think 5 hours for any game is way too short, and I feel ripped off when I complete games so fast (like the last 3 COD games, Heavenly Sword, er... most FPS game in general really).
I think FPS games should be 12-15 hours long if they are a linear style game... RPGs and Adventure games (non-linear) should be at least 30-40 hours of storyline, but at least 100 hours of "extras" like hidden stuff and special secret collectables etc. RTS games can get away easily for 30-40 hours as well since they are a more methodical game you will play for hours anyway without realising.
So, basically... I like games to have some meat to them... regardless of platform. Your GTA style games like Saints Row 2 are great, since you can literally spend as long as you want playing that game if you don't concentrate only on the storyline, but you can smash through them in under 20 hours if you want to get it over and done with.
I dunno about you guys, but when I play a game, I do so because I enjoy it. I don't play iy just so I can hurry up and get past it and go to the next game... I'd be perfectly happy with a game that never ended... unless you died.... in real life.
