Hell, Phoenix Wright in UMVC3 is considered one of the lower tier characters in that game, but did that stop or lower talks about him, let alone demands for him to return in Infinite? Hell no.
I've got a bit of an argument to support this, regarding Phoenix Wright. Anyone here know Lythero? Despite PW being seen as a bad character, Lythero played him because he wanted to, along with Dante and Viewtiful Joe. Lythero became a nightmare to face for most people. Sure, he had that 'no one plays this guy, how do I beat him?' tech going for him for a little while, but even when people started figuring out how to counter him he was still a monster.
In fact, it lead to other players getting on that level of 'git gud' with PW as well, to where you could find multiple people who were really skilled with PW. Also, not playing top-tier characters immediately makes you an underdog, and who loves an underdog? The crowd, of course. Notice how most people tend to root for the guy who made it so far in the tournament using a character no one even thought could make it that far?
This is the kind of love Ridley and other characters can easily get, and when you encounter someone who beats you with that underused character, you have nothing but respect for them because you KNOW how many hours they put into it to get that good.
Like I’m a Megaman/Mewtwo main and honestly I like the fact that when I go online I’m rarely facing off against opponents that have picked the same character. Because 1. It makes me feel like a special little snowflake for not just following trends and 2. People haven’t faced my character a billion times and therefore are genuinely surprised with some of the moves I pull off.
While I'm not sure it's a GOOD thing to feel like a special snowflake, I understand that feeling that comes from playing a newer character. The problem is that it's a fake feeling: you feel like you are actually getting good with minimal effort put in when it's actually just that players who are much better than you in general don't have match-up knowledge yet.
This leads into something that I very much dislike, which is people who make content eventually complain about a character 'being bad' just because the newness has worn off and people have learned to counter the new kid on the block. It doesn't mean the character is bad, it just means that you need to put in actual effort now to advance rather than piggyback off of a lack of experience on your opponent's part.
As for characters who aren't played as much but aren't new, this is a similar sensation but without as much negative connotation: If you whoop someone with Dan Hibiki because you play Dan and this guy rarely faces any, it's no longer about the player taking advantage of knowledge that players possibly don't eve have yet, but it's now on your opponent's shoulders to remember his counterplay for your lesser-played character. That is feeling I can respect.
Kudos to playing Megaman btw. I've tried him but I need a balance of projectiles and other attacks and his kit just doesn't appeal to me. I feel like a mostly brain-dead ape every time I pick him up.
I get excited about pretty much any character joining. Seeing a trailer for a new smash character always makes me smile, no matter who it is, unless I have a personal vendetta against the character for some reason. (This has only happened twice with Corrin and Bayonetta for the record. It'd happen again if Erdrick got in or some FE character)
For me, I get excited because of possible moveset potential. I didn't want Incineroar, but his moveset is awesome, so it made me excited. Slime and Steve would inherently have really unique awesome movesets. I got excited for Joker despite never playing Persona or SMT. I just like smash bros
Oh my god, someone who I can relate with! WOOO!
My reason for getting hype at most character reveals is a combination of seeing the cool stuff the new character can do and the idea that someone somewhere really wanted that character in the game, so I get hype because someone else got what they wanted. I was hype all through the reveals and as another someone who has never played SMT or Persona, I lost my mind because even I knew this was big.
