I think it is a particularly hard character to build a game around. Danger/conflict for Superman boils down to a binary question - is kryptonite present or not?

I think it is a particularly hard character to build a game around. Danger/conflict for Superman boils down to a binary question - is kryptonite present or not? I think a later Superman game (for the XBox or XBox 360 generation, I believe) tried to use the health of Metropolis in lieu of a health gauge for Superman himself, which I thought was a novel idea. There's also a lot of individual mechanics for Superman (flight, speed, strength, laser vision, etc.) that are probably challenging to get right. It's easier to work with more limited heroes.
