In both those video descriptions it says "SimCity is an online
city building simulation game from Maxis Studios.". That kind of worries me.
Also, in the trailer and the 'Insider's Look', they talk about plunking down buildings like in Societies, instead of designating zones like in other SimCity games. I hope that's just for special buildings, and not for everything.
Other than that, the trailer looks great, and I'm interested in the game
