For many years nothing happens with Toribash, than, all of a sudden: new versions arise, new items and stuff, it goes on Steam for GreenLight program...
Only one conclusion I can make from this: Whatever amount of money TB was earning for Hampa, dropped. TB is in danger to be shut down, and developer is now doing everything to rise interest for the game and start getting enough money so it won't happen.
Otherwise, all of this new stuff would have been done sooner.
