The game is built around this dude. Who is completely new. So I don't think it's too big a stretch.
It's a wonderful mechanic, but it's really just Kirby's copy ability in reverse. Each capture isn't a whole new character to play as (thank god) - they're essentially one or two special moves that would have been granted by a power-up in previous Mario games. As such I don't see them as making the gameplay that different.
For example... capturing a fire bro in this game is this game's equivalent of a fire flower. Capturing that reptile dude is this game's equivalent of a cape or racoon tail. And so on. And yeah, they're brilliantly done and very inventive, but ultimately they're power-up replacements.
So what's some general consensus on the Broodals? Are these guys some you'd like to see stick around? AKA like future Mario Kart contenders? Or should they be lost to the wind after this game?
I started off kind of hating them and their designs, but they did slowly grow on me over time. I still don't really know how I feel about them, but I don't think I'd mind seeing them pop up again. Also their battle theme is sick.
They were good, but definitely a one off thing for me.
