Originally, there were 3 other options for main characters we considered using
- Young Greg
- Jamie
- Anon
However, they all had a simple problem: They are not Steven, or rather, they are just human. What I mean by that is that Steven can do everything you would need to do in these kind of games. He can shapeshift, meaning that his dick can be whatever size he wants, he can make himself bigger, he is also incredibly strong, being a diamond. He is also connected to everything and very social, so you don't need to find many excuses for him to move around or get to know people, go to homeworld, which a regular human probably wouldn't (maybe in Future they can, but we also wanted to span the OC show).
For the diamonds, we didn't want to just shrink the diamond, we wanted to keep them big, but, in this case, Steven can just make himself bigger, plus there's the RPG element that, although not implemented yet, a combat system could only be done by someone with powers, which limits the options by a lot.
Mind you, you can't change Steven's name here in Gem Domination, though. Even if you could change the name and be an anonymous figure, the whole story would have to be rewritten to accommodate this.
