If the game is to continue to expand and be successful then additional options for character customisation are definitely something that need to be looked into moving forward. There's a massive amount of support for such a move across various threads and it was even asked during the Frankfurt Fan Fest.

As far as something like a bulge slider goes? I'm all for it. It's sorely needed, either as a slider or just enough of a bulge that the character model doesn't look like it has 'Ken Doll' anatomy. I'd point to Overwatch as a tasteful example of male characters having a bulge.
