Game is awesome but there are many problems with multiplayer , like people can join you but then in game itself time and weather is desynced for the host (Like it turns night in 1 minute for the host but for others it's always day). There are also other problems like the settings always reset after you enter the game , push to talk seems to be broken , inventory system needs to be tweaked and many others things that seem not working properly.
I'm pretty sure all of these can be fixed after few additional patches.
