I don't have a PS3 but was considering buying one and getting GT5 and the new nascar game, but I was also looking at just getting TDU-2 and F1 2010 or shift 2 on the PC as I have a nice wheel now.
Normally I look up reviews (and I have) but members here have never led me wrong, I am likely gonna pick up TW-2 at the same time as the racing games. I been playing FO-NV again and loving it but was looking at these other games.
TW-2 seems like my best bet for a good open world rpg, with the abality to be good or bad.
So,
Shift 2
TDU-2
or a PS3, I don;t think ill use a ps3 that much though TBH.
The racing games don't have to be super realistic, I get my sim fix from I-racing now, just as long as its a good solid game. TDU-2 seems like it would be close enough to GT-5 (car tuning options) and still allow me to goof around and just get some use out of my wheel.
