like my old halo 2 days

I'm really missing them. Is there a non-fps pc game wherein I can casually (preferably voice) chat with other players? One whose gameplay isn't necessary casual, but less commanding of players' focus so we can shoot the breeze?

Usually if I just want to chat with my friend without having to get too invested in the game, we'll just load up a session of whatever MMO we're currently messing around in. I don't really do the whole raid scene, so it's a pretty casual experience.

If MMO's aren't your thing, I've gotten similar experiences from Terraria, Torchlight 2, and GTA V as well.
