Gotham, i share none of your complaints. in fact, i have very few qualms with MHX at all. it plays exactly like it did on SNES, albeit a tad slower, and with the few changes made to it. to me, that's enough to keep it fresh without flat out changing things.
it's pretty annoying that you still have to press dash and jump at the same time to dash jump off a wall, and the Pink Shot got nerfed. but changing the capsules around was a great idea. the Zero Buster is fun to play around with, too. and there's also the aforementioned using multiple weapons at a time and Hadokening Sigma. i feel there's nothing wrong with the new Sigma Stages or the music. hell, i prefer many of the remixes to the original.
i 100% disagree that playing as Vile was the selling point of the game, fun and challenging as it is. the selling point of the game is that it's an enhanced port/remake of Mega Man X. and the game is clearly targeted to existing fans of the Mega Man series.
if you haven't learned to not give a [parasitic bomb] about Mega Man story, do so now. even so, i don't have a problem with any of MHX's story. i mean, it's pretty much the same as MMX's. Day of Sigma is fine. i've even gotten past Dr. Cain's death. i've convinced myself that there's no conspiracy to kill the guy off and write him out of X2 and 3. if a MHX2 were to be made, Dr. Cain would reveal he's still alive somehow early on.
i like this characterization of Vile way better than MMX's "lackey". it makes him feel more unique and important. and as Zan just said, he was like that since X3. i say good job making everything consistent. i don't have a problem with the narccisist Octopus. that had to be done so that he doesn't act the same as the other guys. and you're incorrect about Flame Mammoth being retarded. he just talks slow. just because he sounds like Lenny doesn't mean he's stupid.
if you ignore the changes made, this game plays just like the Super Nintendo game did. the gameplay is fluid, easy to pick up, and most of all, fun. that's the sign of a truly great game to me. it's actually a hard decision for me whether this or the original is the better version.
oh, and i do love Powered Up too.
