Federation Force at least that’s the same exact genre as the rest of Metroid. You can’t compare them. And it’s not like Metroid didn’t have Hunters and Pinball as spin off games earlier. It was really only absent on N64, and on the Wii U but made big comeback regardless.
DKC didn’t have its big come back since Donkey Kong Country Returns! And before that, the only games that really addressed its lore and established franchise elements was DK King of Swing, Jungle Climber and Barrel Blast. These sort of games don’t even get released anymore because PAON is gone from Nintendo.
It just doesn’t make sense DKC is neglected so badly. Mario VS DK also has way more Mario elements in its gameplay, and up until its latest 3DS game it didn’t even have any DKC character outside of DK, who’s not even playable and acted way more out of character than Samus did in a couple of scenes in Other M. Also, Other M was great. And Samus Returns 3DS was still mostly a new game to many.
So yes I have my reasons to be upset about Retro not making a new DKC game. There literally won’t be another studio that will make a new game, while there’s plenty of studios, and even Nintendo themselves who can handle Metroid.
I'm sorry, even if I like Donkey Kong Country more the Metroid, I have to fault you here.
You say that plenty of studios and Nintendo themselves could handle Metroid, that also holds true for Donkey Kong. There is no reason that Nintendo couldn't have another company or themselves make a platformer (especially when Nintendo knows well how to make platformers) the same holds true for Metroid (though, to be honest, Western companies like Retro are probably better choices then Japanese ones for Metroid Prime since Shooters aren't as popular in the East as in the West).
There's also franchise fatigue you have to worry about. If Retro was stuck only making Donkey Kong titles, they would inevitably get franchise fatigue and their games would suffer for it, taking a break is good for a company and its series. Its likely Retro themselves wanted to move onto something other then Donkey Kong for a moment themselves (rumor had it that they were developing Star Fox Grand Prix for example).
Retro never even said they were making a Donkey Kong game, so whatever they would have been making instead of Metroid Prime 4 might not have even been Donkey Kong related so you literally have no reason to be mad that they are developing Metroid Prime 4 instead.
Most well known ? Then why has Donkey Kong ALWAYS been represented as DKC Donkey Kong in Smash?
Whatever point you tried to made failed with that. I can’t take you serious about this anymore. A Metroid spin off shouldn’t count because it’s a multiplayer, but Mario VS Donkey Kong TOTALLY COUNTS of course even if DK isn’t even playable, there’s no DKC elements, and DK is the antagonist.
Tropical Freeze sold too much for DKC to be neglected like this.
Mostly because that was the design of Donkey Kong at the time and has been DK's default design since DKC, even appearing in Mario spin-offs such as Mario Kart & Mario Party.
DKC isn't being 'neglected', it had a game released in the past 5 years, its FINE, it doesn't need a release every year or every two years, its not dead, its not hibernating, its perfectly fine and will get a new game when its time for one. I wouldn't be surprised if it gets another new game before the end of the Switch's lifespan. I mean, the gap between Donkey Kong Country Returns and Donkey Kong Country Tropical Freeze was 4 years and I know its been 5 years since its release, but it also had its upgraded port to tide over DK fans and keep the series relevant.
