The Genesis Shadowrun is a RPG, the Nintendo version is a run 'n' gun game with a RPG flavor. They are very different games. Both were very enjoyable, but I like to be more involved in a storyline and its characters. I prefer the Genesis version for this reason. For what it's worth, I think this is the best console RPG I've ever played.
Graphics are good overall.
The exception being the trips into cyberspace where the graphics are excellent. The visuals and attack animations while on a Matrix run are top notch. Control is excellent. If you get your character geeked on a run, it will be because you made a serious error in judgment, not poor control. Sound is good.
