For [1] Some scenes during a gameplay will have sex scenes or CGs too. Even you don't want to. Like Arion x Heyden, Korg x Logan (Bottom Logan route), Ste x Logan (Bottom Logan route), Blake x Logan (Bottom Logan route), Barrel x Logan (Bottom Logan route), Everett x Feliar, Everett x Booner, Red orc x Northcrest soldier, etc. That why I said make a new game would be more easy lol.
By the way, your ideas really interesting. >:D
