If there is a game that you really want to play, you will need to run it yourself. And if you can't find people IRL as in your case (Did you try to see if your LFGS has listings of some sort?) then you could look online.
That said online groups are often terrible. However if you thoroughly and interview every person, you can probably find a group that you can stand and doesn't flake out evenetually. Roll20 is a big avenue for finding players, though you shouldn't entirely discount Fantasy Grounds and Mythweavers.>>49073693
Already explained that your best avenue is getting people who you actually like to play it with you. If you are like me where your friends are revolted by the idea of playing tabletop games, then you are out of luck. I would at least advise you to not play D&D or whatever game with people who you wouldn't hang out with normally.
