I've been posting on message boards forever (Game FAQ, IGN, RealGM to name a few), and reddit was my next foray. I was pretty sad to hear about the API news and I saw Lemmy mentioned in one of the threads, so I decided to join.

League of Legends + TFT for me. I've played since season 3 for LoL and for TFT, I grinded so many games to hit challenger before I quit.

I really like posting in my local team's subreddits, as it really does feel like a tight nit community. Especially since my teams are not that great, the ones that actually still participate are the diehards.
