I do not believe that the Xbox 360 actually exists since I have never seen one. Therefore, it follows that neither of these games actually exist either. :fresh: For what it's worth, I thought the graphics looked better on NFSMW.
I played Need for Speed for about an hour and the graphics are sharp and detailed, and the game will keep you busy for a while on the single player mode. I didn't try any other modes so I'm not sure about the replayability factor. I have PGR3 and I must say it is very well put together. So if you're leaning towards a RR6 type racing game, why not try out PGR3 as well?
If someone is going for a Ridge Racer Style game then they wont like PGR that much. PGR is trying to be an arcade version of a simulation racer. Ridge Racer on the other hand is a pure arcade game to it's core. I've yet to try the 360 version of NFS but I played the PSP version and the xbox demo. I think the game has issues that are anoying (the game punishes you for doing good and rewards you for doing bad). As for length. All 3 games have a serious amount of stuff to do. None of them will leave you feeling like you wasted $60 on a 5 min game.
While I havent played RR6 specifically, Id buy RR. The demo that I played of NFS just wasnt fun for me, though im not as into arcade racers as I was.
i like ridge racer games , pgr looks line, but i dont really like simulation that much... it isnt as fun.
PGR definatly isnt a simulation, though its not as arcade-y as the others, it falls inbetween, thats why I like it
