The idea itself is a great one, however, actually making it happen would require one heck of an effort, for various reasons :
1. Vstep make simulators, not simcity style games,
2. Vstep and EA are two COMPLETELY seperate companies
3. the gameplay would be very hard to impliment in a way that will make the game commercially viable, after all, why make a game if your not going to make money from it?
4. EA dropped development of the sims city series ages ago, and I highly doubt they'd want to restart it...
FYI the forum is wholely owned by VSTEP B.V.
