Depends on the day - where I have the day off/nothing to do, I spend far too long on the PS3...... it's so addictive O.O I probably spend more time on it than 3-4 hours lol, not good
Once I start playing a game, I spend every min of my day on it.... That's why I always be scared of installing a new game... lol, I can't help it...
It is funny but for the last time I spend the days more and more for working and studying instead of fun and playing. Don`t know why but I am ok without games
