I think there's a potentially decent game here, but it's buried under a veritable mountain of flaws. This is a JRPG in the most barebones sense. There's a shallow story that backs up 20 hours of running down hallways and repeated floors. All the while you are hit with lengthy random encounters that will remind you why they're a thing of the past.

The combat is the bread and butter of the game since it's what you'll spend 90% of your time doing. I would say it's decent and requires a bit of strategy. Stat buffs and debuffs are really ambiguous and I never fully understood or took advantage of them. Hyper modes are neat but they feel weird to me since they're limited but the game expects you to be using them constantly.

I like the new characters a lot but they're underutilized story-wise. Spider debatably being the only exception. I'd die for Marino.

Mega Man X: Command Mission is a pretty mediocre RPG, the story isn't very interesting (although I appreciate that they finally made an X story that doesn't involve Sigma), the dungeons are frankly a chore to get through and the random encounter rate is mind-numbingly high, so why the above average score?
Simply put, the combat is fun, every character feels vastly different thanks to the action trigger mechanic which has you doing special inputs or little minigames to do a more powerful attack (think special moves in Mario RPG) along with the hyper mode mechanic which makes your character more powerful for a set amount of turns, sure towards the end of the game I just stuck with a team of X, Zero and Cinnamon (especially once I get the secret hyper modes) but it's still fun to experiment with such a large cast of characters.
Also I'm a massive fan of the X series so that helps too.
