atleast both had the same protagonist, a walking cock without personality or any lines.
For Japanese it may be popular to have a mute protagonist to "project" yourself in the role, but from an european standpoint, i prefer to have a protagonist with a personality, a face and maybe one or two quirks.

Just Imagine Rance from the Rance series as a protagonist. Hell that would be just amazing. i would love the hell out of every interaction between the characters.
