Just bought a couple of these with some friends just to give it a go. We looked into it six months ago and laughed and never gave it a second glance. The prices are just way too ridiculous for what you get in any other racing game. At the current 80-85% off sale, it becomes reasonable. We picked up some cars and tracks that we don't have in our other games.
So far, I like the sound and the FFB is better than PCars. The dedicated server is annoying, but works well for what it is. Options are a bit lackluster.
My entire race group (half of whom won't buy in, even at discount) are all of the same opinion...the pay model sucks. We'd have all bought this game if it was normally priced and had reasonable DLC packs.
Shame too, as I think this could be a much more serious contender if it wasn't stuck behind the paywall structure (and F2P turns off a whole lot more people than it seems to turn on). I'll still pop it on and enjoy it on occasion, but without my buddies all buying in, not much reason to drive it. Still, got more time last night than I have in A/C.
