Also try the Genesis/Mega Drive one if you haven't. It's a very different game and while I think the SNES version looks and especially sounds better, the Genesis one is mechanically deeper. Matrix interactions in particular are night and day between the two.
¿So how does Shadowrun on the SNES hold up? ¿Is it worth playing still today? I've played the modern incarnations (Dragonfall, Hong Kong) and loved them much for their themes and aesthetic, but just the tactical gameplay could be fun too.
