SAO just has the problem of going on too long with the same content. Same MC means the MC has to start acting denser than a black hole for any new problem to arise, cause you gotta be hella dumb to fall for the same shit 3 times. Same general plot gets stale, particularly when you use the highest stakes possible first.
It would have been much better if it stopped following Kirito when the title game was shut down, and any subsequent games follows a different MC for each. It enables a fresh take on characters and makes any problem that arises for the new MC feel appropriately scaled, since it's never plausible for them to say "oh ya, it sucks, but it's not as bad as that last time when losing means I die."
But fuck it, it prints money.
I feel like SAO is too repetitive for me
"Hey look a new game"
"Oh cool, I bet we'll have tons of fun!!"
*Ah something NOT FUN*
