Though we had some videos comparing the Ghosts 'n Goblins & Ghouls 'n Ghosts series, this is a new video looking only at comparisons of Ghouls 'n Ghosts only.
From Wikipedia: Ghouls'n Ghosts, originally released as Dai Makaimura, is a platform/run and gun video game developed by Capcom and released as an arcade game in 1988, and subsequently ported to a number of other platforms. It is the sequel to Ghosts'n Goblins and the second game in the Ghosts'n Goblins series.
