Not surprising. I'm already seeing the early warning signs of 4's problems in Prime 3. The linearity, the AI constantly telling you where to go, an unnecessary travel mechanic to get to different areas.
This is overblown, but I'll agree that going any further than what Prime 3 did is a bridge too far. That said, Prime 3 wasn't a game in a vaccum, it was the end of a planned out Trilogy. It was a finale featuring multiple planets getting the Tallon IV treatment, the stakes had to be raised. How do you suppose you travel to multiple planets without a space ship? How do you fight a war without talking to anyone? Whatever brief moments of NPC communication there are boiled down to the plot or plot-related elements. At worst I would say the Aurora Unit is a more ignorable version of Navi from OOT, who already isn't as bad as modern NPCs. It sure as shit didn't tell you exactly how to get somewhere whether you wanted to know or not, all the hint systems in the Trilogy could be turned off in the menu. I would say for a game which introduced all the things that it did, voice acting, numerous NPCs, an interactable gunship,
Over 4 different planets, and a single escort mission - Prime 3 is how you do it without it breaking Metroid's atmosphere.
I would say the singular planet Viewros has less consistancy in and of itself than all of the various planets you explore in Prime 3 combined. Prime 3 put in the work to make and flesh out (with lore, music, flora, fauna, and architecture) the planets Norion, Bryyo, Elysia, Phaaze, and even the fuckin Pirate Homeworld. Do you know how awesome it is that someone on the dev team thought, "Hey, let's make an entire space pirate hive planet and go there because it would be cool", THAT is the quality of the old Retro.
I gotta say, I would really like to see an expose on what exactly happened behind the scenes of Prime 4's development.
Because all the signs of a turbulent and messy production are pretty much evident with the way it turned out.
I maintain that Namco likely did something very extreme, whether far too safe or far too Other M-tier. From there Nintendo announced the reboot and got Retro back purely for the name recognition, perhaps to buy themselves time, or because they themselves genuinely believed Retro could do it. From there I think the project was basically put on ice, ideas being spit-balled, staff being hired etc. with no one really knowing what to do or where to go (all the best Prime staff was gone by then). Then Prime 1's 20th anniversary approached, and I think Nintendo got the same idea they used for Grezzo and Zelda - *have a new team remake an older game and thus osmose them into being competant devs of new content*. The irony being I think this strategy failed twice, with Grezzo/Zelda and Retro/Metroid being unable to replicate the quality of the past.
Either way, the Prime Remaster was successfully completed as a "test run", and from there actual development on Prime 4 began, with one caveat. Nintendo had already poured so many shekels into the project that they had some "demands" for Prime 4 thinking it was nessecary to break even. "Make it more like BOTW", "Make it more like Halo". Which is where the 343 hires come in. I think from early 2023 to earlier this year the development was hell, I think good ideas were scrapped for "normie ideas", and all the while the Prime formula was being buried by hollow open world deserts and motorcyle mechanics. Metroid's atmosphere was being suffocated by mandated Marvel NPCs, and I think staff like Kenji Yamamoto were completely confused as to what the final game's vision would be, which is why the OST has no destinct personality.
The game was developed literally by commitee, one studio made the sound effects, another studio made the CG cutscenes, another studio did the voice acting, another studio developed the AI, everything was smashed together from disparate elements. The game was a frankenstein's golem, and Nintendo most likely KNEW it didn't have the 'right stuff' - which is why their marketing campaign for it was god damn DEAD. These niggers knew what they had and decided to cut their losses on it without shilling out for an advertisement campaign. I would bet anything that this general scheme of events is close to the truth of what happened behind closed doors.
