I've been playing a ton of Gran Turismo PSP this weekend (surprisingly, more than Motorstorm!) and I have to admit, I'm addicted. I was a bit unsure about this game at first (no campaign, no online, random selection of cars) but I love the way it plays. I like the idea of having a random car selection after every two(ish) races because then it won't take be days to pick a car. Instead of trying to pick a new car based on 800+ I just need to pick one out of ~25. I've done a ton of races, have about 16 cars (including one minivan!), and can't stop playing. I've got a PSP 2000 and did the UMD install option (which copies 900mb of the game to your memory stick) and it was totally worth it. Loading is fast, and I don't need to listen to that UMD all the time. I just wish I had my Ferrari Enzo, but Amazon didn't send me my DLC code yet.
