If you have a university nearby try checking that out, they often have some kind of /tg/ society (in my country at least). sometimes they even have grills too.

Personally I could never get too into hardcore RP autism like that, though. I sometimes like to make up a story for my character in vidya RPGs but doing it irl with other people is just too much for me. I kinda know how you feel though since I love Riichi Mahjong but don't know anyone willing to learn all the autistic rules.
