The start of a spin-off series of great games and any fan of the Megaman series will love this game instantly.
The graphics by 1993's standards were one of the best and (like I've said before) is better than the graphics than most other Megaman games released recently like Megaman X7 and X8.
The sound is very unique with charged fire shots, individual shot sounds and background music all in one. I enjoyed very much.
The replay value is low because you don't need to go through the whole game again to get the secrets, you can just re-visit the levels after you've finished it.
The story is the highest because this game introduces Sigma and throws Dr. Willy aside. This game cannot be classified as anything but Revolutionary.
