Man, it feels weird to be back in a Geno thread after all these years. It feels like just yesterday it was E3 2013 and I was arguing why Mega Man's inclusion was helping the case for Geno.
It's less about "protecting feelings" and more "preventing entitlement". I think the important thing to recognize here, as much as I hate to say it, is that Geno is by no means a likely character. I don't say this as a "HA, you're never getting your character" kind of thing because, believe me, Geno's been my most wanted newcomer since I joined. It's more that it's far too easy for people to get emotionally invested in an echo chamber like message boards or social media that (in reality) only reflects a small proportion of the player base. The reason people say things like "hype responsibly" is because plenty of people get so invested in the characters, it's taken as a personal attack when someone criticizes them. I've seen it happen far too often.
It's not like it can't or won't happen, I'd be a moron to say Geno won't be added. Ridley, K. Rool and Banjo are more than enough proof against that. I do think he's the only "fan favorite" left that's truly missing, and I really hope he's added post-Pass, because I feel he doesn't NEED his own stage / spirit board like the Pass characters, and can easily be sold with a few SMRPG tracks, similar to how Corrin released on 3DS / Wii U.
The Grinch "Ruse" (which is such a weird name for it) was stupid, sure, but I don't think you can discredit people for believing it. People who were reaching for straws and saying things like "GameXplain and Source Gaming know the Grinch leak is real and are trying to cover it up because they want to keep ties w/ Nintendo" for sure were dumb kids. I'm not gonna act like I wasn't salty when Grinch leak was fake and instead of Geno, there was Plant, because I spent an embarrassing amount of time reflecting on that one, but don't act like someone telling you to temper your expectations and not get too emotionally invested in a game is this act of malice.
