Depends on if she plays or not. If not, then i imagine that you shouldnt talk to her about it at all. If she does, then maybe yes. But im sure normal girls dont find RS attractive.
I'm married to an avid WoW player... what do you think he is doing right now? lol! why don't you try to get her interested in the game, my husband gave me a 10 day trial on WoW and now I'm at level 80... sometimes you may find that you have more in common with people than you think!
Dude runescape has nothign to do with chicks wanting to date you or not. You could be the number 1 player in runescape and the hottest girl in the world could date you. It all depends on LOOKS and personality. Hell i play runescape and my girl is fine as hell according to half the guys in my grade. (10th grade) The only chicks that MIGHT actually care are seriously 10 and 11 year old immature "cool" middle schoolers who needs a middle school image. which is like 1/20 LOL.
ignore that last post, dude they wont care because your playing a game, my sisters boyfriend plays runescape, so do i. If they really care about you, or like you. they wouldnt care if you played runescape. or any game.as long as you dont play it 24/7 and ignore them. ALSO its just a game. you dont even have to tell them about it.
