Changing the formula of a 25-year old series can be a much-needed breath of fresh air when all of its conventions begin to feel too tried. Sometimes change can be very beneficial, such as the case with Metroid Prime, which took a 2D side-scrolling series and made it into a fully 3D, first-person perspective with resounding success. Sometimes, however, the changes just don't work, and you end up with a game that doesn't capture the magic of its original formula, nor the refreshment of its new direction.
Such is the case with Metroid: Other M, a joint effort by Nintendo, Team Ninja, and D-Rockets to blend the gameplay styles of the first-person "Prime" trilogy with the side-scrolling platforming of the originals, with a newly prominent emphasis on narrative and backstory. Some of the new elements and twists work pretty well, but a slew of other problems drag the game's few prime achievements down into oblivion.
Plenty of criticism has already been leveled against Other M, but most of the professional reviewers only complain about Samus's characterization in the new story/backstory, and nitpick a few other problems (like the awkward control scheme). In the end, they still gave high praises to Other M, when the game doesn't deserve anything more than a mediocre "middle of the road" score.
Other M was a nice experiment, but the results are not worth praising. Besides the big issues mentioned above, there are a lot of smaller details and problems that ultimately make the game feel bland, generic, and soulless--almost a chore to play. It's nice to see Nintendo taking risks with such a staple franchise, but I hope they learn the lessons from this one and refine the experimentation process in their next release. More of my review / analysis after the jump.
