My Mum doesn't seem to care much about me playing them. She knows its what I enjoy doing, and I still get out and stuff so thats ok. My Dad is the same, to an extent. Sometimes he'll pass my room, see me playing a game and say "what else did I expect" or he'll say "get out of fantasy world and listen" when he's talking. It does irritate me a bit but not too much. He does play some games though e.g he loves war games and when we got our first console (N64) he finished Mario 64 for me 1 night and taped it for me so I could watch it the next morning.

The thing is though, staying up playing video games is alot better then going out, getting drunk, possibly doing drugs and possibly getting someone pregnant/getting pregnant yourself.

Another reason, I think, why parent's might not like gaming is because of the expensiveness. It all adds up over time.
