This Soldier Blade interview from 2012 was originally featured in a 20th Anniversary e-book released by one of the game’s designers (and ardent fans), Hideki Yamaguchi.

There is also another interview from the same e-book with composer Keita Hoshi, which I plan to add soon. In the meantime, however, I’ve appended a collection of Hideki Yamaguchi’s “design secrets” he revealed in 2011
