Starcraft 2 - worth buying?

[Wyrm]

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.

The recent DMCA revision allows you to bypass copy-protection as long as it doesn't infringe on the copyright. Granted, it doesn't do anything for the online play restrictions, but you'll at least be able to play on that desert island.

Really, though, if you're going to a desert island with no internet, one would think you'd have other things planned than sitting around playing Starcraft 2.

Also, don't forget about Mine Sweeper.

All that being said, I have no idea if SC2 is worth playing; my brain can't handle micromanaging, so RTS games > me.
