they wouldn't really "cost 0" though. it costs money to implement features and make sure they work, even if they use existing assets. i think the big canyon between the character perspective system and advanced free battle is that the advanced free battle is probably going to be quite an undertaking. shoving stretch goals in that space is only going to take money away from developing that.
Sound test should cost 0. It's a menu. All of those things really are incidental. They need to do a better job between 5 and 6.
