Hmm, I dunno, I don't think you can patent an idea per se.. I haven't looked at the patent, but it seems like it would apply more to the arcade wheel / shifter setup than the actual gameplay. Could be wrong though.. I doubt they'll win however, since copying gameplay styles is a major part of the industry.. not to mention if they wanted to enfore this they should have gone after Rockstar and GTA3 (taxi missions are directly ripped-off from CT). Ah well, this has more of a chance than Lady Miss Kier vs. Sega, that's for sure.
