I'd like to start out by addressing the preferred maturity content of my games when I run them. We're all likely new to one another, as well as anonymous. We can't really be sure what age other players are IRL, or what their personal sensitivities may be. What we can be sure of is that Dungeons & Dragons 5e publishes all of their material with big capital letters reading "AGE 12+". For these reasons, among others, I like to keep my games somewhere around the PG-13/TV-14 level on the maturity rating scale. Here's a bit of what that means:
Sexual Content: I have no plans for romantic engagements to occur in this game. They're not pre-written into the story as a plot device. That being said, I have no problem if PCs wish to roleplay romantic feelings with other PCs or NPCs should the situation somehow spontaneously manifest, but I don't want to get too sexually graphic, and if things start turning towards that direction, I'll likely intervene with something to the effect of "your character and their newfound companion head to your room in the inn and shut the door, not to be seen or heard from again until the next morning", and then we'll move along with the story. You get the gist of what's probably going on behing that closed door, without getting into the the "moist" details. I don't anticipate rape or sexual violence being a part of this campaign, and I prefer to leave that sort of stuff out altogether. I understand that topics like that are somewhat embedded in the game in not so evident ways (such as how it applies to a lot of half orc backstories), but I don't think we need to dwell too graphically on the details, if at all.
Language: I don't feel the need to use excessively vulgar language too much when describing actions, environments, or situations. Language sometimes comes up in character dialogue, and and can certainly add some fun "oomph" or "punch" to dialogue, but again, let's try and keep it PG-13. "Hell", "damn", maybe the occasional "ass" or "bastard" is fine, and can certainly fit well with the feel of the game's setting, but let's avoid the excessively vulgar, crass, or graphic language. Let's try and avoid "f-bombs", in other words. No crass or degrading terminology for male and female anatomy. Stuff like that...
Violence: Pretty hard to set a tone or governor on this one, as a lot of this game involves hacking and slashing, bashing things with bludgeoning weapons, setting fire to living creatures. A lot of opportunities to commit and reward violence present themselves, in other words... I suppose lets just avoid descriptions of violence that would fit better in torture-porn media, and if at any time someone is feeling uncomfortable with any descriptions of violence, please let us know, or at least PM me and we'll get it sorted out and toned down to a level that works for everyone.
I don't want anyone to feel uncomfortable with the campaign or our style of gameplay... I don't want anyone's mom to send me a PM asking me what the hell I think I'm doing exposing their 13yo kid to some excessively heavy "adult" material... I just want to play some D&D and have fun.
