Yep, this is the dream. Like >>2507
said, it's about find places we can rip em for free, otherwise we make them from scratch. For human characters, it's actually a bit easier. If all we need to edit is the face, that's stored separately from the model. It's actually the easiest thing to simply pop off the default PES head and put on newly modelled one. It gets complicated when you get to replacing the body.
