There's a limit to the game, on two separate grounds. The game engine's limit on common events/flags/switches will be reached.Is there an end planned out for this game, or is it just going to continue expanding and getting new characters for ever?
And there's a limit on the number of girls the Book of Girls can have, and while there are arguments that more pages could be added and/or how many fit on a page there's no indication Tinkerer plans on doing that.
