Hmm, let's say from the start I'll make an ability for player to beat the boss, which shall be pretty easy - so the game will take half an hour, for example... But I'll put up world which is as large as Earth itself in it Laughing This won't be a short game.
I haven't played full Dark Age, but, from what I see, game will have about 50 world locations, 15 different characters to play and different ways of beating game (not just 1 ending). But that's theory. In practice, I've not yet finished even 1 board location. Laughing
