That's great, but it's all already available in City of Heroes. What CoV brings on its own isn't quite enough. Yes, villainous supergroups can now build bases (like an evil version of The Sims) but they cost so much that medium-sized groups can't use them. And where's the evil? The big selling promise was that you could be a villain, but the worst we could manage was to kidnap ... villains from other gangs. That's not a dark side, that's a shade of gray.
While it can be run as its own game, CoV's true value is as a really big expansion pack to City of Heroes (and you can play both for one monthly fee). And while it's worth its price, it would be even more enjoyable if it was less polite.
