What isn't to like about this one? Terraria is a game that can be played alone, but only gets better when you have a group to play with.

Free. Private servers. Zombie Sandbox. This game has all the makings of a community game and thensome. Perfect for group gaming excursions.

This is a little different of a take on a social game. Instead of working with your friends you engage in a friendly match of kill and don't get killed.

This game is a prime example of a social game. We give it a 10/10. The subsctription helps keep those who would ruin its community away.
