I also don't get it why people do complain on MP. Be more patient. Just enjoy practice, or time trial session on AC, there is still much to do in those sessions and, after all, you can get used to the sim, discover how everything works and it's very good preparation before MP. MP feature wont take long to come out, I think, 'cos I saw Gamescom 2012 conference and there was AC title and racing feature available to test it. Somehow I feel like devs are programmed (or how to say) pretty much all the features, all planned cars and tracks, but they are perfectionists, so they don't rush without releasing everything at one take, so you can't do nothing about it. Even BETA version of the game doesn't have many of errors, problems, and even in BETA game looks fantastic and feels like that.
