Okay folks, I know I’ve been one of the worst offenders, but I’m going to call it now on discussion of weight gain/loss mechanics on this thread.
If anyone particularly wants that feature and/or wants to discuss it further then they can create a new thread, but going forward let’s keep this one to discussion of different body models at character creation, rather than mixing it up with the possibility of body shape changing over time which has no necessary connection with the OP’s suggestion.
