2K Games released a tool that lets you reclaim your BioShock license so you can uninstall the game from one PC and move it to another. It's not needed if you bought the game on Steam, since the Steam client takes care of this for you automatically. The Activation Revoke Tool page includes a full FAQ that covers virtually any licensing issue you might encounter. If only everyone was so responsive to our DRM concerns. Microsoft, are you taking notes...
Hi. Been checking your site for some time now and as quite a busy gamer (one child, one on the way, one heck of a pregnant wife) time is a hot commodity: in light of this, I must say there hasn't been a second I've spent in Bioshock's Rapture that I haven't been happy (surprised and happy, scared and happy, you know, save maybe when trying to get the slot achievement - quite boring) and all thanks to your review. If anyone else is reading this, I can't recommend this magnificent game enough. And your site too.
