Just one small semi-OT comment. I don't think the FZ is hard to learn at all. The FXR understeers like a horse on ice and the XRR has trouble keeping the rear sticking.. The FZR just puts the power down easily and immediately, and thanks to the rear engine (it's a porsche), you can swing it around pretty efficiently (less than the XRR but a lot more than the FXR).
So the FXR might be forgiving, but it's very limited. And then it's slow, too.
And I'm not sure the FZR really behaves like an MR. MRs have a nearly neutral rear and front bias, you can feel the engine right near the middle of the length. In the FZ there's a clear imbalance to the rear. Even if it is MR in overall distribution, you can feel the rear is more dense.
That said, it'd be great to have an MR GTR. I'd say something about the balancing (from what I've seen spectating 5min every other month, it's still not near perfect) but I haven't played in over 6 months, if not a year. [/ot]
