My dad likes to relax by playing Warhammer Online.  It seems like it would stress me out to play that game, but he loves it.  He counts his warhammer online gold as if it were real money.  My mom does not mind him playing it as long as he does not get obsessed.  Some nights he plays way too long and she nags him.  I do not understand the game myself, but I know it makes my dad happy so it must be pretty good. Nothing relaxes him faster than sitting down at the computer and playing his favorite game. It is cool how fast he gets into a good mood when he plays.
