Well i really saw a few improvements that could have been made and we received alot of promises for things to be included that just weren't. In addition, we were severly mislead when it came to some technicalities of the engine a good example was map sizes, where you can only actually make a 1mile square map to the maximum...now for our scale thats terrible. We saw alot of improvment happening but at some point it just stopped and in all honesty its not where it needs to be for a game to be released in 2007.
