Amazingly fun and addictive!
GAMEPLAY: Classic MegaMan fare. It was great. Regarding the map and the mission system, it was a little silly to be told to go somewhere having not been there before and having no idea where to begin looking for it (unless you unintentionally stumbled across it earlier), but it was never too annoying for me. My course of action was always "try to find the area first, then find a transerver to save and take the mission". It worked well, given the way the map and mission system are. As for the different models, they are colorful, detailed, and very fun to play. They each have their own element and useful properties. Personally, I found myself using the Fx model the most just because it allows for dashing up and in midair as well as the fact you wield two sabers. Coolness. Actually, you'll find you use the Fx model to find most of the entrances into new areas. Overall though, the gameplay never lets you down.
GRAPHICS: Good stuff. All the environments are very detailed and immersive. Though they don't really take advantage of the DS' capabilities nor do they appear much different from the graphics of the GBA games (I've seen some of them in action since my brother owns some of them), they still provide an enjoying visual experience. SOUND: I absolutely loved the music in this game. I had forgotten how terribly catchy MegaMan music is! None of the BGMs are really hummable, but you will definitely not get irritated by the music.
VALUE and TILT: Seeing as how this is the first MM game I've bought in at least ten years, there had to be something good about it from the get-go...and I find that to definitely be the case. This game rocks. It's not "just another MegaMan game". So overall, I give this game solid 9's because nothing's perfect or flawless, but everything's amazing. I HIGHLY recommend this game to any MM fan or to anyone that would enjoy a 2D platformer. =)
