Been playing Forza 3 a lot lately, and while it is a fantastic game full of joy and sparkles and rainbows and fuckin' gorgeous vehicle modeling (both interior and exterior), I miss a lot of things about Forza 2, like brake-specific damage/wear and other shit. I am glad, though, that they brought back Fujimi Kaido, and the rewind feature is handy.
I do wish the damage modeling were more realistic with damage settings set to "simulation", though. I played this with a friend, and he and I went to opposite ends of the MASSIVE straightaway on the Ring, and we slammed into each other while both doing upwards of 250mph. That's a rate of closure (and therefore impact) of over 500mph. The cars were still recognizable as cars, and they were even driveable. I'm sorry I don't care if they put 10x the polygons into modeling each and every one of their pretty little virtual cars. If GTA4 can model a totaled vehicle to even the weak extent that it does, I want the Forza guys to do an even better job.
