the closest match to playing this one in my experience is no-mans sky.
light survival, exploring, building, crafting, resource gathering.

The biggest differences apart from cosmetics/settings are that NMS buildings don't do much, the ones in Val are required, and combat in NMS is a joke, here it is harsh and a major part of the game.

What do you mean by "unmodded"? Thought it's an online game. Wouldn't it affect game and potentially lead you to being banned if you mod the game?

the game is unfinished and mods are currently tolerated. There is no 'ban' apart from the player that owns a multi player server can try to enforce a ban if you are causing disruption. It does affect the game: people cheat out some limitations like ore transportation. Its a single player game if you want, or you can play on a server run by other players as a small group. Its not a MMO where the game devs run a big server and monitor it.

let me say that again to emphasize it.
THIS IS NOTHING LIKE A MMO.
