It may be time to retire this category for one simple reason: No one comes close to matching GameStop's selection of new and used video games and hardware. That's why this Grapevine-based company, with more than 1,300 stores nationally, is a perennial winner in Best of Dallas. The clerks know their merchandise; the prices, while not greatly discounted, are reasonable; and we doubt that it's possible to drive more than a few miles in Dallas without being near one of the chain's locations. But why do we love it so? Here's why: We wandered in looking for a copy of the coveted Star Wars: Knights of the Old Republic on the day it was released. "Have you preordered a copy?" the clerk asked. "No," we said, lip trembling, tears welling in our childlike, 41-year-old eyes. No problem. He felt our pain and reached under the counter to find us a reserve copy. The guys at GameStop? They know your joneses, fellow gamers, and they sympathize.
