PRIDE and OneFC definitely have the GOAT intros. UFC has watered down the uniqueness of each fighter. PRIDE had showmanship.
The thing is though I think there's enough beef/drama to keep people interested in watching. Plus maybe there's a bunch of "Just Bleed" type fighters that like the appeal of combat sports.
I honestly don't really find basketball for ME that appealing alongside most other ball sports except football (strategy, almost simulating war) and tennis (agility, dynamic) but I watch it because it's an American past time but I may have just grown out of watching most sports. Speaking of American past time, are people watching baseball like that any more?
Yeah ONE FC goated with their entrances and theatrics but good Lord the commentary and "TeChNiKco KnooCkOwUt!" Annoying ass announcer kills the vibes to a PRIDE FC alternative.
RIZIN should have been the torch carrier, but sighs...not many stars as ONE and UFC.
As far as Baseball...eh, as a marsupial that watch it from time to time, it's a hit and miss to the average watcher. The seasons themselves are too damn long, and despite the new timing of the pitches, the games still feel like slogs go get through.
Don't even get me started with how stupid and redundant the blackout rules are

. Probably worse than the NBA.
