Trove is an MMO (Massively Multiplayer Online) game, meaning there will always be other players ready to fight by your side or help you out with a problem. Other players in Trove will also likely be able to provide you with gear that you want in return for some cubits or a spare item. Building houses or fighting bosses can be dangerous by yourself at first, so you'll want to make some friends quickly.
Players can also create their own clubs that they can invite their friends to. Clubs can have their own exclusive worlds, useful if you and your friends want a world to themselves. Certain items that can normally only be placed in a cornerstone can also be placed anywhere in club worlds.
