This is one of the best magaman games since the x series.Even better than Megaman Zero in my opinion. No disappointment
Megaman ZX cures all the problems of Megaman Zero. Great sound from the DS and the music is very catchy and mixes perfectly with all the action. I always enjoy the animated movies scenes they make for these games but this only has a couple.
I admit the story isn't all that great as I never really liked the whole Idea of megaman NT where a kid merges with megaman to become megaman. Anyway that aside it still looks like Zero from Megaman Zero but plays much more like megaman x as it should have after x6. It's strange but I do wish they would have just continued using x but instead it is a merge of megaman and zero brain chips in an armor for human.
Figuring out where to go after you beat a mission is the only dounfall as it does have a horrible map system but it is very fun and exactly what you would want in an x game once you figure out where to go (gamefaqs has the maps you need to solve this problem).
I completely recommend this one as it is perfect only you probably won't want to play it for a while after you beat it like any of the megaman games. Play it, you'll like it if you liked any of the megaman x games expecially since it seems they won't be making any more x games and this is actually a continuance of the story.
If you haven't played the Megaman Zero games you might wonder who most of the characters are but once you do you realize that all the biometals are actually chips in armor of the copy x's guardians. It's interesting and really looks good.
