I would like to say that, while not a perfect game, I think Mario RPG was an amazing game with a fun story, good characters, and a stellar soundtrack. As far as why I like Geno, he was essentially the earliest "cool guy" persona we really had. He was somewhat snarky, but had good intentions. If it wasn't for Geno, then Mario and Mallow wouldn't know that the Star Road was destroyed, which may I remind you is literally the plot of the game. He has an interesting design that incorporates detachable limbs, bullets, and magic into his fighting style, something we haven't seen since. It'd be nice to see him return for Smash or even another appearance in a new game. As far as Mallow goes, I just remember him being annoying. Growing up, I see that he was interesting and expressive in his own right, but I personally believe he is overshadowed by Geno in most things.
