I finished it. I wanted to go in blind so I avoided spoilers. It's a massive disappointment.
>The first green area is the best looking it's all downhill from there
>The desert is fucking aweful
>The feds range from uninteresting to annoying
>The enemy variety is non existent: the green area seems to have the most, while the rest of the game is mostly grievers and two models of bots. No, I don't count a slight recolor with more health as a new enemy
>The desert feels like it's designed by someone who didn't like breath of the wild but put it in for more sales
>The new weapons are the most generic ones I've ever seen: fire shot? What happened to plasma beam?
>The last two areas before the final boss are long escort missions
>The mine area does the "go on without me" trope multiple times, only for everyone to magically be fine at the end
>The green crystals are the worst padding I ever experienced outside of rpg level grinding
>Because the green crystals and mech parts are limited to the desert, the final fetch quest is mutually exclusive with picking up items you missed or didn't have the right ability for at the time, as almost all those are in the actual areas
>Sylux has no development whatsoever, his backstory is that he's just an ass hole, Samus never wronged him
>The ending is such a massive sudden tone shift I thought I missed a good ending like Silksong. It also makes no sense.
>Unlike the original trilogy, getting a post credit scene is not only 100% items, but also 100% scans
>The important scans aren't a different color unlike like the trilogy, so have fun scanning everything in case something is important
>They forgot that the logbook in the prime games allow you to look at the 3d models of scanned enemies, so that's missing too
>Did I mention the desert is padding? This killed replayability for me. I'm not grinding green crystals again.
