Have you ever heard about City Life?
Yes, this link covers its new version: Cities Unlimited which has been developing nowadays.
The most important aspect of this work-in-progress game is, a large active community helps feed the developement progress of the game with new ideas and suggestions
So, why not trying this with the NBA Live 09?
What do you think?
