Was over the moon when I read this is available to play offline too. Definite purchase for me in that case. It may come out this year, but i suspect it'll drop into 2016 tbh.
I can wait though. Should be epic.
Yeah Oct to Dec is too full of games, Q1 would be smarter. This is the kind of game that you can just pick up and play for an hour here and there for the rest of your life LOL.
I would love for this to blow up like minecraft did, its even more amazing considering only like 5 people are working on this game.
