Dug this one out this evening to have a little go since the latest update, as well as AC Rally which I've just updated in that thread.
It seems to be running better. The handling is great. The graphics are great. It really is like ACC but with road cars. Dare I say it, I even drove the E46 M3 and had fun.
It's frustrating that it's so incomplete, but not because the devs are too slow or anything. It's because it's got so much potential and will hopefully see that potential lived out in time, but because everyone sees it being so incomplete they don't really want to play it yet. I'm quite sad that career mode has been dropped. It clearly had a lot of potential and was a fairly core part of the game, but I'm hoping it's a case of 'it's not the priority right now so if we cancel it, we can always re announce and implement it further down the road' as it's not going to be anywhere near as much fun freeroaming for no reason.
