Meh. The lip-syncing during the song is really bad.
Just kidding. ;) Carmageddon on GOG sounds like a great idea. :) Note, however, that it apparently won't appear until September 2012, according to the description of the video.
It will appear sometime between now and then. We gave ourselves a REALLY LONG delivery window in case we find any bugs we don't know about while we're testing the game. ;)
