Somehow I think we're never going to get a RM like that.
That being said, AtomMan kinda rolls of the tongue better.
In that case, they'll probably save him for the final Classic MM installment.
That said, I do agree with the Atom Man name. In a way, this would be fitting, since the first MM was originally supposed to be a Tetsuwan Atom (aka Astro Boy) game. It'd be like, going full circle, or some such.
As for the whole presentation issue, to each his own. Besides, I think it's silly to complain about a MM game with 8-bit graphics, when the majority of MM fan game projects use those. After all, we're in a generation where people take gameplay for granted and visuals for greatness, while most games are casual in content and/or difficulty.
Isn't good gameplay and challenge the most essential thing?
But hey, to each his/her own.
