Forza might be a good game, but it's no simulation like GT.
Any true racing fans or racers would prefer GT5 because the simulation experience.
You can't even get the true driving experience with Forza.
Wait if you say you can, how? with the controller? or with the crap 240 degree paddle shift only MS wheel?
On top of the accessory support. GT5 refined the physics to a new level with how the cars handle and react individually. The engine sounds of each cars. There are numerous articles out there quoting professional racers get very close times in GT5P with the same track in the same car than in their real life performance.
So far the only things GT5 lack are damage to enhance the level of simulation and a good online support.
The person who said GT5 is more arcadey than Forza doesn't know what he was talking about. Try to drive a Ford GT in Professional mode with the G25, that's a freaking beast to handle.
