I envy you because it's very evident to me that you have an very distinct and elaborate vision for this game. That you have a powerful determination... and I can tell that there is a lot of world building you are looking forward to doing in the creation of this game, but are disciplined enough to understand and know what you have to do first in order to get to the fun stuff of creating. 

Honestly the journey you are on creating this game has got to be an incredible one filled with very hard lows and doldrums balanced by amazing feats and accomplishments when you get it right after so much hard work. 

You are not the type to burn out... You take it as a challenge don't you?
