Maybe the story and character I guess (didn't really feel offended by it), but I think the gameplay was nice being different. Made Samus more of the superhuman she was depicted to be from what I've researched and all. My opinion though.
I thought the gameplay had as many problems as the story personally; annoying controls, (D-Pad movement in 3D, changing your grip) clunky camera, stupid health system, forced pixel-hunting and walking sections, etc.
I think the game is flawed, but the negative stuff tends t oget overexaggerated. I get why since its a beloved franchise, but treating Other M like it is Superman 64 or Ride to Hell is annoying to me.
We'll get a Metroid game besides Federation Force when Nintendo is ready to reveal one, whether it be this year or 2 more years down the line. It has never left their minds as it has been mentioned in previous interviews. The producer of Prime just wants to focus on something he really wants to do (which is Federation Force), so I cannot really deny him that chance if it is HIM that wants to do it.
