We don't even have proper face presets FFS, is it really that important to have a proper body when you cant have a proper face?
And why only fat bodies? I surely miss an option to have a tall character with a slim or at least normal figure, not that bulky hulk-like one we have now.
Also customization in the game is barebones as hell so I don't really see how the lack of beer bellies sticks out either, you only get a handful of face structures and can't even tweak them. It's more that character customization is overall very bare bones for the player model. Things like jaw width, chin pronouncement, cheekbones, etc, usual sliders in many RPG's just aren't here. Considering how rare weight sliders are in RPG's it's of little surprise it's not in either.
