I don’t necessarily think folks should be told they can’t be disappointed if the pick they wanted didn’t get in. I was immensely disappointed when Snake got cut for Wii U/3DS.
However, as has always been, disappointment with Smash goes further than just being sad/frustrated with a lot of folks. Some folks on Twitter still think the SNK leak is fake (wha—?), that SNK sucks, etc...
Now not to sandbag on particular picks- it’s not my intention to make anybody feel bad for liking particular characters- but regardless of how much the internet Smash fanbase (see: loud minority) sees characters like Bandanna Dee or Ashley, for example, their appeal to new players, fans of non-Nintendo games, is incredibly low. Not even Dixie Kong has appeal as anything other than a base roster pick.
3rd parties have wider margins of appeal for a crossover fighter.
In addition, it’s not as if we haven’t talked about this. Dudes have always been trying to twist words to imply 1st parties were in the running. But come on now: Reggie literally said, “Characters not in the series before”, the first 3 packs are 3rd party, not a single repeated spirit, everything is entirely new, etc...
There’s also the fact that the Smash fanbase is notorious, both casual and competitive, for not playing other games. I’ve said it before and I’ll say it again, if Nintendo stuck to games that only “seemed Nintendo” this “biggest crossover” wouldn’t seem nearly as big.
