There is some similarity to Subnautica in that you explore, base build, etc. Its quite relaxed where you can progress at your own pace. I have finished one map and even after having finished a single map I'd say there is replayability in re-doing a map as you can adjust resources rates or randomise ores etc for a different experience. The DLCs add even more content to explore. Multiplayer does work with the Steam version if the Steam user launches the game directly (outside of Steam)
