Do's and Dont's

[Prozac]

What are some of the do's and dont's of making a playerworld
Post do's and dont's in whatever aspect you have experience in.
Such as, what to do and what not to do with Levels, NPCs, Graphics, Events, Gp issues, what kind of people to hire or not hire, what types of stories, themes, quests, etc to include or not include.
I figure we can use a collaboration of many people's experience for what works and does not work in any given graal playerworld.

For example :

Do learn object oriented programming basics before trying to learn gscript 2.

Do not give a staff member more rights than they need.
