I think BRs are fine, I'm just glad that the market has moved away from the BR mania that it was once in. BRs intrinsically need a large player base to succeed and it was exhausting hearing about this "sick new BR" only for it to shut down 6-8 months later
I am curious to see if the BR trend now repeats itself with the extraction genre. I think COD and Battlefield already adapted the mode but I do not know how that went and whether they are still going, but now the first wave of larger standalone "Tarkov-likes" is coming in so maybe there is a new hype forming.
Realm Royale, Battlerite Royale, Ring of Elysium, Islands of Nyne, there's been a ton that have launched and either lost critical mass or been shut down.
