Due to budget, deadlines, and other factors, the girls will mostly have different skin tones (Heather's skin is more pinkish compared to the other 2). I do understand that the lack of different body types can be an issue to some, but I try to make up for that factor with things like all girls being fully voiced by different VAs, they have their own story and motivations for being in the tournament, and they even have their own endings when they win the tournament. Plus, the game features some gameplay elements to hopefully give players additional reasons to play each campaign.
