Not all superheroes have powers if you consider icons like Batman and Tony Stark, as long as you don't consider their money or brains a superpower. Eventually, perhaps years down the road, a ranged, and/or melee, power set where you have no superpowers but your intellectually capable like the aforementioned and can build things...like an Ironman suit. I think that would be legit. Yes, there's a million problems with the idea...like how to diversify your powers within that limited scope, narrow/limited selection of travel powers, and the fact that the devs would have to create the animations that would probably be copy/paste for each character, unless they created a system where, as you destroyed certain types of enemies (like robots) and could loot their physical corpse, or steal tech from other enemies, to get different pieces. A UI to manually create bigger/better gear would be extremely difficult but SO WORTH IT. I've thought about this a lot...as you level you slowly accumulate more tech to build things with, that you could customize (like how Ironman can shoot with his hands and chest and has boosters to fly or a unique UI that comes over the screen to simulate a mask). The more tech you get, the better your 'suit' looks. So a level 5 might have the equivalent of a armored suit that is just a few metal bars and support rods that gives him increased melee strength or something, eventually becoming a full on suit, going from melee to ranged, and advanced travel powers. I am sure this is too ambitious for MWM, maybe if they had the financial backing of Blizzard...but I would pay $$$. Big $$$. Le sigh.
All we have to decide is what to do with the time that is given us.
