I've been hanging around here for a few years, and I've run a number of campaigns using Obsidian Portal to good effect. Up to this point though, I've never submitted any of the games I participate in for the monthly feature. There have been a couple of reasons for this, but the main issue has always been that none of them have met my own standards for player participation. A great campaign is more about the players than the GM, and most of my campaign sites have been almost entirely GM driven.
This game is different, and that's why I'm proud to present, and nominate, "Sins of the First Age":http://www.obsidianportal.com/campaigns/sotfa for featured campaign.
*Sins of the First Age* is a game played in the Exalted Second Edition game system, by White Wolf games. It is, in that respect, largely by the books. You will find no elaborate house rules there, and little in the way of mechanics. Those things are well documented in the published game materials. Nor - for the same reasons - will you find extensive background on regions of Creation taken whole cloth from that material.
What you will find is a volume of content specific to the actions, activities, and adventures in this particular telling of Exalted's greater story. Unique wonders, forged by the hands of divine craftsmen. Places greatly changed - or invented entirely - in the course of our characters' passing. And of course, chronicles of the events that comprise our journey, and all those many diverse characters we have met along the way.
GreatGalby is our primary storyteller, and both Gilheru and I have also taken turns at the head of the table. Our adventures are chronicled on our "story arcs":http://www.obsidianportal.com/campaign/sotfa/wikis/story-arcs page, and each of us has also contributed to the almost forty vignettes you can find in our "adventure logs":http://www.obsidianportal.com/campaign/sotfa/adventure-log tab, which chronicle many key events in artful detail.
On the whole, we've tried to embrace a graphics light, "content rich":http://www.obsidianportal.com/campaign/sotfa/wikis/main-page approach to our campaign, and I couldn't be happier with the results.
We all hope you'll enjoy a glimpse into this world we inhabit.
