It's not so much a game's length that I'm getting sick of, though... it's more so the propensity of save points. If I only have an hour of game time, I won't play games that I know are very sparse on the save points (Infinite Undiscovery, FFXII, where I was waiting an hour to find a save point)...
Definitely. I wanted to get to bed one night because of work the next day but was stuck in the middle of Lost Odyssey's big-ass funeral sequence which I think went for about an hour.
exactly. i dont even play LO on weeknights anymore because at best i've got 1-2hrs free to game and I don't want to get stuck doing something i cant save. so my weeknight games tend to be things like XBLA, or Fallout 3 or Midnight Club where I can start and stop as I please.
