What multiplayer game has a great community and can be played casually and still have fun?
I mostly can only play on the weekends, but sometimes not even then. But I wanted to play a game where I can engage with the community and make new friendships.

However I keep reading how some of the more popular games are filled with toxic players.

Any suggestions?

Minecraft, Habbo Hotel, Pingu Club and such, I guess.

Team Fortress 2 has quite toxic players from time to time, like me. I am not there to make friends, but enemies. And then I blow them up.

SWTOR is pretty much toxic, especially its pvp folks.

edit: Some of it is funny. I have a habit of listing gear drops on the ingame auction house for the items default prices to help out my fellow players. I actually get in game emails complaining about my pricing.
