I have played many a city simulation in my lifetime, and I want to suggest/hope that you guys will implement design philosophies that pay homage to Sierra Studios/Impressions Games.
Those city sim games are by far some of the best, funnest, and value I have ever played.
A lot of folks tote around the notion of copying or cloning, when in reality there are just some proven things that have been pioneered to work. When I see some things implemented from say something you see in World of Warcraft in another MMORPG, I don't see copying outright, I see using what is proven to work.
Windows 8 is a prime example of reinventing the wheel and disobeying what has been a proven pioneered concept: The Start Menu/Desktop.
I might catch some flak for this but I just wanted to air my opinion and suggestion. Impression Games has made thee best City Simulations ever. They are hands down fun, well put together and have a knack for strategy and thoughtful play.
They may have made multiple variants of the same game but I view it no different than buying another car or house. They may not look the same, and have a different coat of paint, but there are things under the hood I just outright expect to be there and function the exact same way.
