On steam, if you need a new addiction buy it. First game in a long time that I played 5 hours straight amd forced myself to stop. Had tetris-effect that night while I slept. First game in a long time that I happily restarted to simplify or correct my layout. There are already mods made for it, big one is Bob's mod, people compare it to tekkit vs vanilla mc.
