This is a -5/10 hot take, my boy. You keep arguing about more liberal ideas, yet when it comes to someone talking about what they personally want you tell them to play more games and change their opinion?
Let me give you a personal example.
I was born in 1991, so the 80s era of gaming other than a sliver of Megaman, Pac-Man and fighting games are lost on me.
I never played Ninja Gaiden in any form unless you count playing as Ryu Hayabusa a little in the newer Dead Or Alive titles.
Crash was never in my taste, but Spyro is to me as Crash and Banjo are to some of you guys, which is why playing through Reignited has had highs and lows for me due to those rosy lenses.
I'm actually down for Sephiroth with my new-found love for FF7 but I must say that he doesn't seem feasible outside of an AT or Boss or Stage Hazard much like Ridley got up until recently.
Nightmare isn't my favorite Soul Calibur character, but I agree that either him, Siegfried or both are the perfect Soul Calibur rep and I would love to see them...but I kinda have fighting game bias and it feels like 85% of the Smash fanbase doesn't want more fighting game reps.
I love Sol Badguy but Guilty Gear is one of the fighting games titles I do not have a history with and I feel like the more anime-esq fighting game characters would be a backseat for the more renown ones, but I wouldn't hate Sol or a GG rep at all. "ROMANTIC!"
I have no attachment to Tales Of outside of my friend Leena, to which I have to root for Lloyd and I also like his design better. Yuri is alright and he feels like he would potentially offer a more traditional samurai playstyle based on his art, but I'm pushing for Lloyd BABYYYY~!
I love Dante despite never truly playing a DMC game in my life. His cocky attitude and ridiculousness and weapon variety are incredible and I think he would be an amazing inclusion.
This is like me telling people to go play more SNK games so you can now like Terry. While that is something I did, it was more of a 'Hey, respect the legacy, you bloody zoomers.' then anything else really. People are allowed to enjoy what they want and they don't need to play anything, though I would encourage someone to play SMRPG before hating on Geno, so I understand where you are coming from but the push for personal diversity here kinda smells.
If it was more like 'Hey, these games are good, so here's a recommendation AND you may learn to like the character more' that would be different, but this feels more like pushing someone to play these games so you can be justified in your own stance, and I don't like that. Glitch doesn't have to agree with you, and even with my small list of wishes for Ultimate Geno is number above all the others. I just recognize legacies when I see them.
