So, which is the Simulator King (excluding pc games)Forza Motorsport 3 vs Gran Turismo 5?
I like your question, being a GT fan, but this is a pointless comparison to do. What the hell is a guess gonna prove? We know very little about GT5 and that alone makes a Forza/GT comparison pointless to do since it isn't fair for either side. We don't even know how many racing series GT will have or what the damage modeling will be like or even the quality of the online play. There are more details available for Forza 3 and it wouldn't be fair to GT, not to mention it doesn't really show what's better.

Ask this question in September 2010, where both games will be available and everyone can get some real hands-on experience on both.
