1: The system has slots for characters to fill. So the player can fill whatever slot they want. The eventual plan is that any open slots monsters can fill themselves if they wander by and want to join in. So yes. Futas can fill every slot.
2. We have no plans for pov right now. But maybe we can. I dunno. Testing will be required.
3. Nope. Not a breeding sim. 100% not in the plans for the base game. Once everything is done and the game is fully released we can look into it.
