Great game! ... ,but a bit short
games pros: great graphics (for the time), easy controls, has cinematics, both characters u can choose are completely different so there is replay value, soundtrack is pretty good, lots of extras besides the bosses, zero is playable again.
cons: game is really short, some of the bosses are way to easy, mega man's armor makes the game even easier, zero has no canon anymore, very little cinematics, its hard to really understand the story since there is no explanation from x3-x4, sigma has to many forms (that could be a pro for hardcore people).
in summary I'd say definitely get this game (if u can find a copy) and if u do it'll probably be for a low price in stores. You wont spend so long in this game (unless you replay) so take your time to finish this game and you'll get the whole experience.
