What game has the weirdest/nicest/meanest fandom?

I'm a casual Half Life enjoyer. Spent some time on the subreddit and man is it off the wall.

Tunic has an interesting fandom. That writing system has inspired a lot of cool stuff. The subreddit is censored six ways from Sunday because of how spoiler-sensitive the game is, but I have to wonder what random passers-by must think.

The Undertale fandom has permanently put me off trying the game. It's not really my kind of game anyway, but I enjoy the soundtrack.

Minecraft has to have had the biggest demographic shift in its player base I've ever seen. I bought the game when it was in beta. Most fans were adults who were able to give a random Swede 20 bucks via PayPal. After the game's release, and especially after the console ports and eventual MS buyout, the average age got younger and younger. I miss the old Minecraft forums.
