I live by Potranco and 1604, there used to be a 3D games but it closed recently, they had imports from Japan
There is a independent game store on SW Military Dr, maybe they have something.
In San Antonio, the Blockbuster on Marbach and 410 has God of War 2, Kingdom Hearts, and other good PS2 games for $2-$3. The 360 games were $6.99 for games like Army of Two and NBA 2K8.
