Forza 3 was only in development for 2 years :), GT5 spent more than twice as much time to make...
And I thought ppl were comparing it to Halo?
Yeah and GT5 has set the gold standard of 3D gaming, a category those games cant compete in.
Forza walked away with multiple awards with higher score on on Gamerankings and Metacritic just saying.
Thanks for ruining this thread. Yep, Forza 3 is a better game because reviewers said so, just like Modern Wafare 2 is a better game than Halo:Reach
Seriously, reviews mean nothing because they are all subjective. Everyone should have his own opinion after playing both GT5 and Forza 3. And I doubt you have played GT5. Some may like Forza more, some GT5, none of these games is objectively better than the other one.
