Starcraft 2 - worth buying?

[VinnieJones]

(a) It has pretty tough online anti-piracy protection. You have to set up a batle.net account and register the key to play at all. Then when you play it is by default with an internet connection. You can play offline, but you need to re-register the game online every 30 days, so don't expect to go off to a desert island without internet access for a few years and bring along SC2 as your one computer game.

This is some of the biggest @#$%^&*( I've seen yet. The federal government needs to step up and make a ruling on behavior like this. Stuff like this, and limited reinstall really bother me. Nystul got it right, this is a lease not a purchase. Arrrrrrgh!!
