Limits on municipal efficiency are far more often social then technological. For a trivial illustration, watch "Jamie Oliver's Food Revolution" on Hulu. It shows, on a sub-sub-domain, the role that regulations, entrenched powers, lazy participants, and disinterested constituents play in preventing sweeping and self-evidently good change. At one point he's trying to shift an elementary school to healthy food, but this means a lot of non-finger-foods, so he wants the kids to use a knife and fork. An appalled lunch lady scoffs, "Do you let kids use a knife in England?" A bewildered Oliver responds "YES!" and she demands documented proof. And this is in the US, where overt corruption is arguably less rampant than elsewhere.
Without resolving some of the problems above, technology won't fix much of anything at all.
Anyway, not sure why this discussion needs to be whether we consider this a "serious" game or not. I think it's a fantastic idea, and its execution will determine how fun it is to play.
Cities get a bad rap. About 75% of the world's people live in urban areas (at least in 1st world countries) so of course they consume 75% of the world's energy.
