I don't think Futa-ring is that hard to master. Since all the coding is done you can just rework the art pieces that are out of date or simply add more. I really liked the gameplay of the game and I'm a huge fan of tactical RPG so I don't think it needs much work either. So essentially the game just needs more content and that's pretty much it. Aside from that, I think making a Futaring 2 is better than reworking the main game
