MGR has missions that restrict you from using any of your wigs or special blades and trust me they are hard. I also wouldn't use the word mediocre. The game was built around the concept of actually cutting things and it does a damn good job of it. Zandatsu is very well integrated and gives the player what it set out to give. If you don't like it than thats fine but don't go calling it names because of your opinion.
If I may butt in on your conversation for a bit, as a man who put in about 100+ hours to MGR, and still replaying it on PC with 20+ hours and counting, I want to express something.
Caiden, sorry to quote you, this is more of a general post that uses yours as a starting point.
Zandatsu ( and by Zandatsu I mean the " Cut AND Take" mechanic, not free cutting ) is the biggest problem in MGR's combat. It constantly clashes against the difficulty, by giving you a free full health regen for every enemy you can down, and doesn't blend in at all with Raiden's combat flow. Zandatsu is basically a 5 second cutscene that restores both your health and Ripper meter fully. It is actively encouraged with score incentives, and has next to no disadvantages aside from forcing you to watch the same two animations over and over again. I expected Zandatsu to be a buffering action, taking cores from multiple enemies and storing them to either use as HP regen, or boosting your attacks somehow. But nope, it's a %100 HP medkit that every enemy in the game carries. Don't know why this is groundbreaking for so many people.
Now, if by Zandatsu you mean free cutting mechanic, it is purely a spectacle device that's forced by the narration, and was extremely under designed in MGR. Let's take the first, most obvious use of such an attack:
-Cutting enemy limbs to either disable them, or take away their offensive options: Now, Ninja Gaiden 2 and onwards meddled with this by giving incapacitated enemies kamikaze attacks that forced you to prioritize them. MGR has no such thing. Aside from GRAD's and Mastiffs, every enemy is rendered useless by cutting a single limb, which is very easy to trigger no matter your upgrades or choice of weapon. It also gives them a last, pathetic attack, that at worst stuns you for 2 secs and does comical damage, which afterwards causes them to despawn. Narration wise, pretty wacky and almost funny. Gameplay wise, irrelevant. And certainly not something unique to MGR.
-Cutting the environment to your advantage: Because they wanted to reach 60 FPS on aging consoles. environmental destruction is severely undercooked. You can play the game 300 hours and never once use the environment to displace your foes. And that's its only application. You can only DISPLACE them, not damage them with pillars or falls. Physics are non existent, environments are as drab and barren as they can possibly be, and objects that are cut lose all their weight and shape, rendering them pretty useless for combat tactics.
Cutting up foes and bosses to 20918398 pieces is fun, for the first 10 times or so, but after that it loses its novelty, and adds no practical advantage to Raiden's combat arsenal. Cutting someone to 2 pieces is equal to cutting someone to 2000 pieces.
If you enjoy it, awesome, I do too. But don't go making up Zandatsu to something it really isn't. It's a novelty mechanic imposed by the original dev team on KojiPro, and clashes CONSTANTLY with the base combat approach Platinum took ( which by the way, is one of their weakest efforts ).
I really like the game, and I still replay it with joy and will continue to do so long after people praising MGR forget it ever existed. But it's been painful to see people trying to elevate this to something it wasn't, just for an imaginary rivalry with the DMC reboot.
