My only problem with the character creator is the inability to end up with a muscular character. I'm not talking about different body height, but just different body types, or 'builds' so to speak. I'd like some muscles if that's what I want to go with (or athletic, it doesn't have to look like a body builder). A lot of NPCs in the game are actually very athletic or have obvious muscle mass. But V is just very generic.
So yeah different body types (without changing the height) should be possible.
