Thanks for bringing this to attention to Swallows, and thank you to this forum for supporting Time Stop RPG through word of mouth and its creator Swallows (he's a hella neat guy) . You discovered this market fraud that would've gone undetected if you had not stepped in and complained about censorship.
Repackaging someone else's work while changing nothing at its core and slapping a filter on the naughty bits, effectively creating less content than the original, then selling it for twice the price, without even consulting the creator...man. That's just dirty.
I mean, who the hell censors a NSFW game that is specifically meant to be NSFW?
Disco Inferno, let me know the price you paid on DLSite for it, and I'll refund you that amount, because good god, no one should ever pay for censored content.
