Wow. Hearing these tales, it's not so surprising that people are reluctant to publicly release. All kinds of chaos ensues.
It's a pity that ended so badly, since if it had been a success with proper covers et al, and people not losing out, then it may encouraged future releases.
And I've got Yakumo's covers, they are indeed very nicely done. I hadn't realised what a prolific player he was in these circles.
