I honestly think 2 characters could be hype to end on as long as they choose certain ones over others. With how much we've heard about Kencineroar however, there's gonna be a lot of salt if they're the last two.
I'd have to agree on your point about the modes. Gives me hope that For Glory will be something more complex than just "hey we record your wins and losses".
True, but in the grand scheme of things you've got a ballin' roster.
-Every veteran in Smash history, which Sakurai confirmed they were highly requested...because they were Smash Bros and all (mostly) loved within their own fandoms.
-Ridley and K. Rool, the two big guns of Smash Bros. speculation and big bads of two iconic franchises.
-Isabelle, a modern face of Nintendo in one of their highest selling IPs.
-Inkling, the face of a brand new IP that took the world by storm.
-Chrom and Dark Samus, two more fan requests that come from beloved games such as Awakening and the Prime games.
-Simon Belmont, a character from a series that inspired the indie game market with games based on it. And Richter because he's handsome.
-Daisy, a prominent and popular Mario character.
-Ken, the original clone character in the fighting game genre itself.
-Incineroar a brand new creature in video game's highest selling media franchise.
Either way you slice it this base roster is insanely good. Sure, some requests will miss out, but hey ho if nobody can find satisfaction among these
74 characters then there's really no pleasing them I am afraid.
