We played AD&D 2E in school after lessons, although sometimes teachers were not really fine with this and forced us to go because these strange board games are creepy for non-knower. We had stable team of few people and some outsiders often joined but gone away after few plays. MTG also was somewhat popular but it was too costly, especially in these times.
Some people from our "team" also played Battletech and Mechwarrior RPG then, because some guy discovered it by chance.
I may say that Russian RPG scene couldn't develop fully because these games arrived in country in 90s, when computers and consoles (especially consoles) became popular, so it was rather obscure thing to do. Who will play with pen and paper when you can play videogame, except some hardcore strange guys? There were LARP movement of course, although they mostly drink alcohol and used funny swords made from some trash (I was on their party once). Don't know about local Russian RPG systems, they surely existed but were too unknown at that times.
Fun fact: we had IT substitute teacher in school for few months, some young student who wasn't popular and kids often tried to joke about him in different ways, and he was pretty angry. After some years (when he already gone from school) we discovered, that he was the main translator of AD&D manual to Russian, and also a known person in that community. So, we played used his translated book not knowing that he is near.
