I don't think a person has to buy this title any longer. It's not for sale anywhere and available for free and legal download. In my opinion a fun game and funny.

That said, I'd prefer the free and legal one. Where's that?
And FWIW, I'm plying it under Ubuntu and the Wine app launcher w/ Winetricks installed. On a netbook w/ a single core Neo and a couple of Gig's of memory.
