I really want this game ! I can't wait to see and use the glassbox, and the design / user-interface looks awesome. The fact that you see the quantity of water in the earth when you plop a watertower, or quantity of electricity you'll generate when you plop a windmill over a hill or not... it's just awesome.
I wish they had bigger maps though. 'cause those ones look small. And I really hope –but with the always-online stuff it may not be possible– that we'll be able to create content in a year or so. Using the STEX or some market inside the game (so the creators could be paid/rewarded if they want to, we're in a capitalistic world), I don't care, but something.
