saying that I had just forced someone to his knees and cut off his head with two swords.
See after I say that the texts stop, occasionally I get one more mentioning restraining orders. So your half way there, be yourself if she likes you she likes you*, just relax she's already coming over. See how it goes. Whatever you do don't huff, say your doing it wrong, grab the controller and say "like this". Also wear clothes, don't assume.
Even though this won't *technically* be a date, it sure will feel like one, and I want us to have a good time
No, just no if it isn't a date don't over think it and treat it like one just go with the flow.
I think it'd get boring if she started losing over and over...but I dunno.
Nope, she will win a fair few, either because you let her or because she's better than you take both with good humour.
Best advice I can give you is to ignore every single response you've been given here, especially mine. You've already managed to get a girl to come over of her own free will, with the promise of one of the nerdiest things in existence. Most should be getting advice from you.
*Unless yourself isn't great in which case be someone cool, but not Shaft cool.
