If it wasn't for the ridiculously tiny city sizes I would probably check it out. I like how pretty much everything is actually a real time simulation now.
The face palm no buy moment for me when was I read that the game runs EVERYTHING on a single CPU core (with the exception of 'audio and rendering' that can be offloaded onto another thread). I couldn't believe it when I read that, who releases a game like this in 2013 and doesn't make it multithread-friendly?! Any RTS screams for a quad core, so one would think a heavy simulator like this would be a no brainer...?!
Really shot down my hopes for an increase in city sizes any time soon.
