Finally getting around to playing this... Been amazing so far, not that I'm surprised by that in the least. I do think its better than Forza 3. (but I haven't done any side by side comparisons with it.)
Oh, getting rid of car level for straight manufacture affinity was an awesome choice... I sort of drove a car in 3 till I max leveled it (which never really took long) and then moved on to another one.
Anyhow, I sent a Club Invite... Hopefully, the powers that be are still responding to invites. (Yes? No? Maybe?)
BTW; For those of who don't know I started the CAG Club in Horizon so don't hesitate to join it when/if you pick up Horizon. (Which I recommend. Its a hell of fun game and one that the demo doesn't really do justice with.)
