I doubt it is true, but I would be legit angry if this was be the Animal Crossing Items rationale. Fire Emblem and Final Fantasy swap out of their entire cast of characters every match (with just the occasional direct sequel), yet they are still allowed multiple repetitions from precisely the same game. Zelda has sooooo many one-game-only characters that would still fit great into Smash, just examine the roster of both Hyrule Warriors matches.
The"hard r" is not even close to the worst shit folks used to state. Honestly the fact people find that word offensive today is hilarious for me because of how absolutely tame it seems to me relative to this older things.
4chan, Xbox live chat, gamefaqs, smashboards.
And it was everyone, not just Esam or Hbox or Mango, everyone in pretty much every gaming community talked just like the kids from South Park and worse, all of your currently favorite players over 20 did this.
That is why you'll hear some self censorship from everyone on twitch cause there are things we used to state that Twitch will flat ban you for and if you are raging all your angsty teenage anger is exactly what springs to mind when you would like to let lose a series of insults. Being a grownup is just with the self control to not state that and say something less offensive or nothing at all.
But man I would not want to become a young teen today. Our shit was only starting to be on the world wide web back when communities have been smaller and we could go delete stuff we said or used different names for everything. Now if you are even decent at whatever everyone understands who you are and screencaps any mildly offensive thing you ever say.
Man if they could have been in some of their high level halo scrims I was in back then everyone there would be perma-cancelled.
My issue was only with the Fire Emblem franchise, as most have stated. I love Ike and I am glad he's in, but he sure does complicate things. Fire Emblem won't get more than 3 repetitions unless this game has 50+ characters, and I think that it's too varied a series for many of its reps to be blue-haired sword users. Frankly, what could simplify matters was if Marth just didn't return, but he's too important to the series and Buy Nook Miles Ticket he is a veteran(for the record, I am glad he's back, I am just saying it would simplify matters if he wasn't).
