If you're looking to make friends with strangers, I'd suggest Planetside 2
It's a shooter MMO. Think Battlefield on steroids, but with medicore graphics.
Find an outfit (ie clan). I've been in several and they've all been full of friendly, chatty types. Granted, those were all based on the Australian server, but I see no reason for it to be different on the US/EU servers.
Look for outfits who have a Teamspeak server and require members to use. Those are generally the ones who value communication.
The downside is that the game has been out for a long while and much of the remaining population are veterans. So gameplay-wise you'll be jumping into the deep end. Which is full of sharks.
If you want to play with existing friends then something co-op is always a good bet. Left 4 Dead is still the gold standard in that area, although the games are rather old. There's also that Vermintide game, which is basically L4D with a new coat of paint.
Oh, and if you like RPGs with turn-based combat and have a friend with similar tastes then get yourself a capy of Divinity: Original Sin. It's co-op is very robust and the game has that slightly emergent and chaotic nature that makes for laughs aplenty.
