I'm currently waiting for the June 7 release of GTA: San Andreas. Yes, I already own this title for PS2. Yes, I'm going to buy it again. Why? Well, for as much as I enjoyed SA, it had problems. For one, I really wish the textures were better. I also was rather annoyed at all the slowdown whenever things got a little too hectic. I know it isn't the developer's fault. The PS2 just isn't powerful enough to do any better. My PC, on the other hand, is more than capable of running that game at full speed.
I'm also looking forward to what the mod community has to offer. Vice City spawned some pretty interesting modifications (cars, characters, new map areas, all kinds of good stuff) and I can't wait to see what they do with San Andreas.
