I think it's important to emphasise some policies that you feel make your game different from other games.
I'm a bit of a perfectionist so I tend to always think about how the things around me, even if already very good, could always be made better. If you are too then I'm sure you've played on games and thought, 'OK, this is neat, but I wish ...' Add those policies to your game; the wishlists, the divisive ones. The controversial ones.
Be Excellent To One Another is honestly a policy I don't at all care for. Not because it's a bad policy, but because it's cliche. What does excellent mean? Whose excellent are we talking here? Be specific.
When I read a game policy that makes clear they will not tolerate sexism, racism, homophobia etc., tolerate OOC harassment, sexually inappropriate behaviour, paedo shit β while some might think these things shouldn't need to be said, as far as I'm concerned they really do, because the handling of these issues historically on other games I've played hasn't been perfect.
Being specific in this way also tells me something about your values as a staffer, which will make me feel safer playing on your game and likely be a draw in and of itself. After all while your role as staff isn't to be my best friend, I think being able to actually like, approve of and respect a game's staff is always good for player morale and comfort.
You will scare some people away β but are those people you wanted to attract in the first place?
