I thoroughly enjoyed the first 3 Primes but even way back then I felt the action in the game was too slow. I remember back in the Planet Gamecube days one of the reviewers commented that Samus felt like a tank and that always stuck with me. Despite its glaring flaws I enjoyed Other M more because the action was so exciting. The Prime games had better controls, art direction, voice acting and story but in Other M, Samus just felt more fun to toy with. That was more fun to toy with despite that mandatory stupid sideways Wiimote.
With Link, Mario or Donkey Kong I feel like I have a ton of control to make a satisfying spectacle out of my own actions. No major set pieces or story beats are needed, they are welcome of course, but the "mundane" actions with these characters are very satisfying in a way that 1st person Samus has not been. Or rather it's not that 1st person Samus is not satisfying to control, it is, just not as satisfying to control as Mario, DK, or Link.
In the Prime games I love the feel of the grapple beam, wall jump, spider ball and boost ball. Unfortunately they are mostly context sensitive. I loved that in Prime 3 the grapple beam was used to snatch shields from enemies and thank goodness that is back. I was always a little lame to me that the grapple beam couldn't be used to latch onto almost any surface. I wouldn't mind the use of a 1st person Hook Shot or 1st person Web Swinging at my leisure. It's just more movement options that would almost certainly speed things up during combat and traversal. I don't know how much it would break the game either since we were allowed the Screw Attack at any moment we chose.
Now with all that said, I am looking forward to this game as Retro's track record is spotless. I'm not hyped yet but the overall packaged of the Prime games has always been a worthy purchase.
