Downloaded it this morning. Ran two races with the Alfa MiTo...so far seems pretty good. Runs better than RR3 does on my iPad 2 (frame rate sucks lately for that game). IAP seems less restrictive. Multiple currencies exist, but you get some of each every time you race, not just at predefined levels. The physics are good, but are still not totally "real". It is tons better than 2K Drive, though. (I want to love that game, but I just can't.)

I am going to play it for a while and see what's what. Will it replace RR3? Who knows? We'll have to see what the rewards are for the new TT tournaments before I decide if I am going to give up on RR3 for good.
