Straight up, I like the whole concept of the science system and I think it adds another new dimension to the game. Adding anything new to the island that has to make you rethink your whole strategy as far as the workings of your economy can only be an asset. Making you think is the real basis of what makes the game work...BUT and what a real but this is, what a chance you had BB to kill 2 birds with one stone that you let slip by.
Level 50's are over it and are sick of waiting for legitimate new content. The "fairy tale" looks like dying before you even get it of the ground because of your lack of foresight..how easy it would of been to do this:
level 51..new adventure..reward bookbinder
level 52..new adventure..reward simple papermill
level 53..you know where I am going with this, you could of incorporated the new science system and opened up the game and made it new and fresh again for level 50's and let the lower levels know that it doesn't all end at level 50.
Just the rambling thoughts of a player fast reaching the status of "jaded"
