I'm still under the belief that had a £30 ($45) full retail release happened, we wouldn't see it until next year. I'd prefer three $15 episodic download releases (still totaling $45) releasing from this fall through next Summer/Fall rather than waiting. Also, I think that had SEGA gone with a retail release, we probably would have had the old physics engine (as there would be no leaks to criticize). SEGA is smart to do episodic and then maybe a full retail release. That way, superfans would be spending twice as much. Devious? Yes. But smart (in a devious sort of way). I would gladly buy a disc version after the DL version if it had cool cover art and exclusive content, maybe an art book or cool tin box or something.
