In my middle school years I could go from 9 at night till 630 in the morning on weekend nights with any game. Nowadays (senior in HS) I can only go maybe 3-4 hours tops then I need to go to bed or go outside.
I don't love the games any less, just enjoy taking little breaks so the game is more "refreshing" (if that makes sense) when I come back.

On topic: I usually don't play constantly enough where I'm forgetting buttons and such, but last night (coincidentally) I just got done playing skyrim, went to bed, and dreampt about looting a dungeon with my family. Weird, huh?
