She dosen't mind.she used to ***** at me a little when we first started going out together (6 years ago) but now she made her peace with it, she's even interested in some games (mostly RPG's...)
The worst that happens is that if i play too long, she's sound asleep when i go to bed, and it's on purpose

i know now that "i'm going to bed, i'm reading a little but i'll probably be sleeping in 30 mins or so" means "last call"
Besides if she wants me to do something she just asks, i pause, do the stuff then go back at it...
