To be fair, the Genesis version of the game was closer to the PnP game than the SNES version was. Granted, the rules for both the games were... inaccurate at best (and the Genesis version had the worst ending to a video game I've ever played through, dammit), but the SNES version did a fairly good job and the Genesis version had the basics of the setting down to a T.
Besides, if we're really going to bitch about Shadowrun, we all know which version deserves our ire the most - the recent FPS clusterfrag that has absolutely no connection to the game whatsoever.
