It is on Linux but it seems that there is bad performance, I will be easy to install it with Heroic Games Launcher if it is available to download with gog (other launcher does not support official account, only account from the launcher).
This game is good for free-to-play player but with premium it's very very good, it seems like a management game if you don't want to farm, there is PvP, island and even if it's not via the stuff, there is a lot of way to became stronger or more efficient
