Player Safety
The SCP universe can be host to horror, whimsy, and fantasy. You are free to explore these elements individually or altogether, but you should keep in mind your players’ comfort when dealing with certain sensitive content. Some SCPs may need to be off-limits, or otherwise certain abilities modified to better suit player comfort. At the start of your session zero, begin by talking with your players about what sort of content and tone they feel comfortable with, and what is off limits.
If a player tells you something is off-limits, it is off limits. You are not entitled to a reason. Make a note of what they told you, and move on.
Tabletop Roleplaying Games should be a safe, fun, and positive experience for everyone. With a little bit of work up-front, and an awareness towards the sensitivities of the others at the table, it can be. In addition to a session-zero comfort check, it is encouraged that you make use of the X-Card system or the Support Flower System in order to provide clear boundaries during play and ensure everyone has a fun and fruitful time.
