A shoutout goes out to Darthdevidem01 who suggested this comparison.

Both games are the symbol of racing perfected on their consoles and rightfully so. While GT has been a long running super successful franchise, Forza has made a fantastic debut on the 360. Discuss which game looks better folks (and please make your vote clear).

I didn't get as many votes as I wanted in this comparison but the margin was large enough for me to decide a clear winnner. GT5P wins it 16-3.

Gran Turismo 5: Prologue

Forza 2

Thanks for the shoutout! It was my honour!

ANYWAY

GT5:Prologue looks better....thats where my vote goes!

Npz bro...my vote also goes out for GT5, I can't wait for the full game to come out!

GT5P 

Gran Turismo 5: Prologue

No contest.

Gran Turismo 5: Prologue

GT5:P

The pics for Forza are so awesome that they don't even show up

Edit: there they are. Forza 2 for sure

Oh wow. Way to pick the worst possible combination ever. It's not interesting when one is the clear winner.
Forza Motorsport 2 is using the same graphics engine as the original and Gran Turismo has always been about pushing the graphics.

My vote goes to GT5: Prologue.

I'll be shocked if someone actually votes for Forza 2.

Forza 3 looks next gen to Forza 2.
