I don’t know how popular of an opinion is since I don’t see it brought up much, but while watching some videos about people's predictions for the 25th anniversary I saw a certain Poketuber bring it up and he seemed really serious about it and I think there are way too many ways it can go wrong.
I don’t want any more of the Gen 3 and prior type distributions. In a country and time period where physical Toys R Us and Gamestop are barely clinging on to dear life it just doesn’t seem fun to me. He said it would be cool if they had a special Mythical Pokemon for the 25th anniversary that was distributed this way so kids could see how people who were born in the 80s/90s got Mythical Pokemon. Combine technology being easier to access in rural areas so kids from there would know about the event but couldn’t easily reach it, brick-and-mortar toy stores being hard to find even in urban areas, and kids not being able to drive, and I just think in-person Mythical distributions are one of those things Pokemon just shouldn’t go back to, like HMs and single-use TMs (At least the SwSh system lets you get another TR infinite times in one playthrough if you run out)
His other idea was the Pokemon was released to the general public about a year from now in the “normal” way like Zarude but in February they’d have a contest so only 1,000 or so people could get it in spring/summer but then everyone would be able to have it. With cloning and hacking becoming so common, I don’t think the Mythical Pokemon would feel “special.” And considering what happened with Mario’s 35th anniversary and FE1, people would accuse Game Freak of triggering that FOMO feeling to pressure people into doing the event, even if it was free to sign up. The Poketuber pointed out that since SwSh had so much controversy even compared to Gens 5-7 which are slowly being vindicated by history and 2020 was their first off year since 2015 so they have extra time for whatever they have planned for the 25th anniversary, this is their big chance to win back people who disliked SwSh and to me doing an event like this is too risky. It’s just too easy for it to cause another controversy and if it happened and caused a controversy, it should have been avoided.
