It's a tricky question because of the two different modes in my game and both are completely independent from each other. I'll say story mode has advanced a third of the whole story I want to include, but with FAP mode is impossible to tell, since is non-linear, I can add as much characters as people want me to as long as people stay interested in my game. Of course the game will end at some point but is not something I am thinking of, I'm having a lot of fun doing it.
