Looking for an open-world, multiplayer PC game?

- I want a game which is open-world, and you can also talk to other people (similar to Minecraft or APB)
- I'm not hugely into RPGs (the millions of fantasy/dragon/world of warcraft type games just don't interest me that much)
- My laptop is pretty average, so it couldn't run any really big games

Any recommendations would be great, thanks.

So you want an open world MMO but you don't want an RPG? Maybe GTA 5 when it comes to PC.

Space Engieers and 7 Days to Die are open sandbox games. Multiplayer as well. Read up on it

Firefall. It's kinda a fantasy open world first/third person shooter.
