First Forza game I'm considering not getting, at least not at release.
Played the demo and something just doesn't feel right to me, cars feel like massive, heavy, unstable boxes, messed around with all assists too. Did a B2B with Forza 5 and the difference seemed massive in handling, the amount of braking it feels is required to get round even the slightest corner seems excessive. F5 in comparison felt "right".
Even though it's a limited demo, I get the feeling it will be pretty dull and drab in terms of SP yet again, with a tedious progression structure (basing this on the "Volumes" i.e. race series divisions it shows off).
I may still give it a chance but I think I've been spilt with the likes of Driveclub and Horizon 2 which are how console racers should be IMO. Also there is plenty of other stuff coming out which will hold my interest more than this.
