People used to form “gaming-clans” in order to find people to play games with to begin with, and that structure for a community around a game is likely to become relevant again simply to be able to fill matches with people who you can be sure are honest players.
Unlikely imo, because modern game devs have been killing the viability of that for years. User-hosted servers are gone, crossplay is reliant on SBMM to be realistically possible, and private matches often block players from receiving XP and rewards because they’re worried about FOMO and people getting too much fun without spending enough. Even CSGO got an update in the months leading up to CS2 where they removed the ability to earn drops on community servers, driving another nail into the coffin as one of the last kinds of these games that still retain the mere ability to run servers of our own.
