Yes that's all good and cool stuff. It's almost like an RPG twist to your car. A bit like trying to have a unique toon in an MMO.
However, this just shows how different the 2 games kind of are. GT5 is based on manufacturer cars (as is Forza, I thought) and "limited" by the tech, styles, mechanics of those cars in real life. GT has always been great for tuning your car but it's limited by the "universe" the game is set in.
I'd be pretty sure there will be leagues in GT5 but again based around the limitations of what a real world car is meant to do. No point racing a blueprinted souped up Toyota Yaris in a league of American muscle cars.
Another however, I love the idea of an AH in Forza - again, an MMO concept in a way. Maybe I need to see the E# conference again and understand more how the tuning will work in F3? I'm intrigued.
