I practically ruined high school because of Morrowind and owned a PC and Xbox version of it as well as Tribunal and Bloodmoon. That game was my basis for fantasy world building and I used to spend most of my class time drawing large maps and crafting rough (very rough) sketches of characters. I haven't found a world since then that has captivated me the way TES 3 did.
On the side I'm learning to use Libgdx, a Java game framework, and have never quite given up the dream of building a whole universe.
I'm not familiar with CK but I would definitely learn Papyrus.
I'm excited to see this project flourish and hope to be a part of it!
