Keiji Inafune is routinely credited for creating Mega Man, and it's true that he both shepherd the series from soon after its genesis and drew the art that adorned its original covers. But the director of the first two games in the franchise is Akira Kitamura, and in a newly translated interview over at Shmuplations, he shares insights into his design process for the original classics in the series -- techniques that still hold water today.
For example, Kitamura (pictured, above, in manga form) analyzed the action games at the time to try and figure out how to design the experience he describes in the quote above:

The full interview contains a lot of insight and history both, and it's well worth a read if you'd like to learn more about the genesis of one of the defining action game franchises of the 1980s and 1990s.
