@Dshoonmaker and I are working on my game Runelands (in development). It's a sandbox survival derivative of minecraft but with a focus on magic, exploration, art, and an eye toward optimization.
We haven't gotten very far yet, but it's going really well—check out the procedural terrain @Dshoonmaker has created for us!
Some people have asked, 'why not just do a mod for minecraft?'—well, this game is NOT minecraft. It will do things much, much differently, and beyond a similar blocky style will be a fundamentally different game.
This is our instagram account if you're interested in staying connected to our project.
We are also looking for additional help on this project, if you're interested see my post in the professional trade subforum.
