I remember trying Guild Wars 2 and thinking every other player might as well just be a bot because nobody interacted. :(

I'm sorry that was your experience, but this is very much opposite of mine. Not only is the game still going strong (new expac came out like two weeks ago btw, and it's pretty good!), but in all my years playing (and that's been since Day 1), I've had so many fun interactions in the game.

And that's without even counting the ones with my guilds. I've even had some fun chats in ranked PvP, the saltiest place in the game. I'm playing in European servers, which probably doesn't change much versus NA, but yeah, there are often conversations going on in map chat, or locally, between total strangers. Also between teams in WvW, during events, during festivals, waiting at the Wall after the Chak Gerent...

It's a very friendly community and I encourage you to give it another try! And yeah, if you can find a guild suited to your tastes it's even better!
