I'm a huge Metroid fan (pseudo is shamelessly inspired from the Varia suit and Samus is a hunter... duh huh), but I've never been completely on board with the Prime art direction as I think it should go back to its horror/tension/sci-fi roots (Super Metroid). Don't get me wrong, I've loved Prime 1 and 2 and it was my most anticipated game on GC back in the day (even dreaming about it...).
But, something in the Prime series was missing. Prime has almost nothing to do with the original ambiance from Alien, and it's a shame. You won't ever be afraid in the Prime series. It's atmospheric for sure, but it leans towards wonder instead of dread and horror the series was originally known for. The music is totally different in tone, the graphics show absolutely no gore (while they did on a SNES system...) and nothing is oppressing in the atmosphere (aside from some part of Prime 2).
And don't get me started on the gameplay, which was a good thing on its own, but was absolutely not a good 2D to 3D translation.
Samus agility is completely gone, she's a fucking tank. The lock-on is a disgrace but was a necessity with the abysmal second joystick of the GC gamepad. They kept the exploration part, but totally shifted the main gameplay element, leaning towards analysis and puzzles with a bit of assisted shooting. To this day, this is why 2D Metroid and Prime have almost nothing in common except the exploration part.
Other M was a good step in the right direction but was ultimately mediocre for other reasons.
I've been longing for a 3rd person action/platformer/shooter (akin to Returnal for example, without the rogue aspect and some light BTA additions like in Other M) with more emphasis on the platforming part. And I've been deceived by Other M, which is ok but really not what I wanted for that IP, being constrained by the Wii remote and Sakamoto (lastly) idiotic ideas.
Also, I felt like Metroid Prime 4 was more beautiful in its reveal than in the second trailer. Weird. Hopefully the difference is meaningful on Switch 2 (if there's a Switch 2 version, but I don't see why they wouldn't do that...). On another hand, I'm not that excited by ANOTHER Prime and they showed nothing different from the first 3 episodes.
But I'll still buy it anyway...
