I'm not talking about his peak, Mega Man is still a character that lives on, he's still got his comics, he's got a anime and movie coming up, he's got games that while cancelled were still a thing like Legends and Maverick hunter. What's Banjo got? Rare Replay (Mega man also had a collection all to himself just recently) and Nuts and Bolts like 7 years ago which everybody hated.
Mega Man is still relevant. Banjo is not.
"Relevant"
There's that word again.
You can't be relevant, you have to be relevant TO something.
Saying something is irrelevant is purely subjective, it means "this isn't relevant to me" it's a vague, unsubstantiatiable generalization.
And everything you said is wrong.
Megaman hasn't had a game in years, all the games he had in development were cancelled by Capcom due to them fearing it would ne unsuccessful, and his first appearance in a long time in SFxTekken was seen as an insult by all Mega Man fans.
His franchise is so dead, people threw money at Inafune hoping Mighty No.9 turns out well.
Sound familiar?
Oh, but because Mega Man is now in Smash, "he's always been relevant" and never faded in obscurity for all the years people were crying for new MM content.
Banjo's situation is literally the same as Megaman's in.the gaming industry, but because people have hindsight bias, they claim it's different.
