Wow, this is pretty impressive for a mall game store. About 100x better than any of the Wizards of the Coast or Game Daze places that plague every other mall in the valley. Unfortunately, their popularity and massive selection hamper them a bit when it comes to accessibility. We went by on a Sunday and they seemed to be having a Magic tournament which took up the bulk of the store's available space. We had to squeeze by gamers to look at all of the games.
They had a few games that we had been looking for but were "out" of some of the more common and popular ones. The guys were pretty helpful and had some alternative suggestions but none of their suggestions really fit what we were looking for.
This is a good place to go if you are already risking your life by going into MetroCenter but otherwise, I'd go up the street to Imperial Games.
