HI XenoBunny - interesting question, I couldn't find much in the documentation - so I went looking in the R20 Terms of Service and found they list a 'play nice clause' part of which reads as follows: " You will not post or otherwise submit any topic, name, material or information that is ... defamatory, excessively violent, harassing, inappropriate, indecent, lascivious, lewd, obscene, profane, racist, unlawful, or otherwise objectionable. This is in relation to using the forums and VTT but I can't imagine it wouldn't also extend to creator content. I would suggest contacting R20 directly with any material that attempts to push the adult envelope - especially as a new creator, there are probably reasonable concessions. It is not others standards you need to address, but theirs and that may be decided on an individual case? In general if you think you have to ask, the answer is generally no but if you don't ask you won't know. RPG has a lot of elements that fringe on horror, debauchery, torture, terror, lust, ravaging and rampaging - I mean even though one of the core concepts of RPG itself is centered around killing - a lot - all the time - even WOTC is very cautious about addressing even the basic representation of demons, sorcery, satanism. I'd be surprised if they went anywhere near nudity anymore. It's an interesting dilemma that what began as an adults game with so much adult content, is now also aimed at inclusion by children and encourages their involvement causing a lot of gaming companies to tone everything down and pare everything back - because D&D et al are at their heart adult, violent games, and often times because our fantasy hobby is represented managed (and sustained) by companies who must be very careful with PR - we have to share the same space and marketing space of and by adults with kids. If you're trying to create the broadest customer net possible then you don't want to offend anyone, especially today when a single incident can kill your business. I think some blood, guts, bones, bodies, zombie gore, torture devices, savage traps, skeletons if stylized into a fantasy appearance, are considered acceptable by many gaming companies, - but anything suggestive, especially overt nudity is a landmine.
