I don't thinkyou need a "good" resume to get a job with that place since pay is generally minimum wage or at least local market rate for retail. Basically it helps tons if you have good people skills and customer service skills when it comes to dealing with the general idiotic public. :)
Of course having knowledge across all gaming platforms won't hurt either, but don't make stuff up to pretend to be more knowlegable then you really are. If you tell them that Hello Kitty Adventure Island is the bestest game ever and are serious, they may laugh you out of there.
Although, once upon a time I had a little fun with McDonalds when I was younger and had a better job but did this for a laugh. I interviewed with them and made sure that no matter what they wouldn't hire me by telling them pretty messed up things. That I could only work 3 hours in any given day and could not work consecutive days. That I required a salary of $90k a year and that I needed to be able to say farewell to every Big Mac sold as I saw them as a loved child/pet to me. I think the manager got a kick out of it just because of how messed up it was, but it was something fun to do when I was bored.
My pokemon brings all the nerds to the yard. And they're like, "You wanna trade cards?" Damn right, I wanna trade cards. I'll trade this, but not my charizard.
