When I was a student, used to stay up till late at night, sometimes even all night to play games to level up char, earn exp, find golds, etc in rpg games (Diablo 2, Baldur's Gate 2, Icewind Dale, etc).

After entering university, still play when got no assignment but tend to avoid rpg games coz cannot commit long hours to it (play a few days, then stop do assignment for a few weeks, come back totally forgotten where I'm at in the storyline or lost interest already).

Now working, play during off-work hours if not too tired, only certain games I like will I re-play twice in hard mode or find hidden items to unlock achievement. Most just play on normal for storyline and be done with it. Multiplayer totally no time, just single player campaign
