Anyone who is thinking about buying this game should be aware that the netcode/multiplayer support for this game is an absolute train wreck. The developers at Stardock and GPG are working feverishly on it, but it's still awful. Be prepared to spend 30-60 minutes in the lobby trying to iron out everyones connection issues before actually getting the game going.
Then, when someone rage-quits, a bug causes everyone else in the game to be dropped. Fun! I'd recommend waiting a couple of weeks before buying. Right now, this is barely playable in pubs and only really fun if you've got an in-house game of some kind (LAN, forum, friends, etc).
Edit: As aside for the pirates, your online experience will probably be even worse unless your torrent also contains Stardocks most recent beta patches. LAN with friends might be workable, but that'd be about it.
