I`m playing it right now and all I gotta say...
mind = blown
Don`t worry, Im not a full blown pirate - I preordered a copy too...
but damn... this is great, youtube videos/reviews etc.. do NOT do it justice. This is something you need to see yourself on the PSP screen to appreciate.
Sound is extremely good given it only outputs stereo too; on my headphones I can clearly hear the VTEC crossover on the NSX I'm driving
