I used to own the Genny and Saturn copies of the game and they did impress me, but I always felt that the Genesis one was the best representation of the game as far as closeness to the original in gameplay and control. Damn shame those tools at Sega felt the right to charge $100 for the game...I got it from sega-parts.com probably 5-6years ago or so for $20 new, and that is worth it.
