Not 100% what to call this, its deifantly RPG, and will have MMO values to it as well. Its another early access that promises a lot, but seems to have delivered a decent amount from what I can tell so far. It also has a single player version, with up to 64 they promise private server multiplayer. But they want to make an MMO world for it as a well, wich will be always ongoing, and well more massive. Here is a trailer for it that got my attention: Oh it has the whole do something to level it system, with traits tied to the skills, so mining makes you stronger etc. Also unlike Rust and Dayz has a morality system, if you get below -50 alignment you become flagged forever more as a criminal, and its not longer bad to attack, or rob you. It has piety system as well you can pray for more good points once a real life day. The data will be server side not client to slow down hackers as well.
