Abulafia: Abulafia is a special kind of wiki. Instead of just adding articles and entries about whatever, you can use it to generate random bits and pieces for whatever kind of fiction you're working on. It was designed with Role-Playing Gamers in mind, but would work equally well for playwrights, authors, and so forth.
The GM's Parlor: An archive of maps, adventure ideas, rules, creatures, props, and more -- all designed to make your role as GM easier.; Has a great collection of mapping graphics for Dundjinni, Campaign Cartographer and Gridsmith.

d20 System Unofficial Wiki: The purpose of this site is to be a single resource for players and DMs on such things as, but not limited to, common rulings on Gray Areas of the rules, advice on how to build and roleplay characters, the creation of new feats/items/classes, new uses for old skills, reviews of a d20 book you liked/disliked, or post rules questions. If it's d20, post it.
D&D Wiki: It seems that many creative and original ideas that are posted on the Wizards of the Coast's D&D Message Boards are lost forever.

If someone thinks something is overpowered or underpowered they can change it, and make it exactly as they see it would work best.
The Hoffman Studio's d20 Wiki: The purpose of this Wiki is to create a form for d20 players to post, edit and share alternative rules for different d20 RPGs.
