If you are a player or GM, you’ve probably read a lot of advice on how to make your gaming more fun. It almost all boils down to one thing though and that’s my gaming maxim: don’t be a dick.
Yep, that’s all there is to it. Don’t be a dick and you and your friends will enjoy your games a whole lot more.
If your GM tells you his game is about heroism and camaraderie and you insist on making a character who is a loner and an assassin, you are being a dick.
If your players tell you they want a break from the current campaign and you respond to that with a total party kill, you are being a dick.
If you beat someone in a competitive game and you then gloat and rub their faces in it, you are being a dick.
Don’t be a dick. It’s that simple.
