I think Kunos really need to work on bug fixing and features. I am a little annoyed that the title has reached V1.1 and is still having issues, crashes, broken menus, missing basic features etc. Its a good title overall, and the driving feel is great, however its something of a rough diamond at the moment and the devs really need to step up and fix whats already there before adding anything more.
Considering the team and their goals, I'm guessing Assetto Corsa will always be a diamond in the rough. Luckily for me, I haven't encountered any crashes or broken menus or things that seem awfully wrong, but I just do my own little thing and haven't even begun to use all of the game in its entirety.
What I *would* like though, is an easy to use multiplayer mode and LAN support. Whenever I look up multiplayer for AC, I find guides and port forwarding and whatnot and don't bother anymore.
