Now that June has come and COTM has been awarded to Kettle's Rise of the Dead, I would like to submit Keryth987's wonderful "Shadows Over New York":http://www.obsidianportal.com/campaigns/shadows-over-new-york campaign for June's Campaign Of The Month.
This campaign has everything - Graphics, videos, logs, etc.
But most importantly, it contains a TON of information, wonderful characters, and an interesting storyline.
The site itself is fairly easy to follow, with a clear, concise, unified, and attractive design. The Characters include a ton of details provided by the campaigns players (I assume). The NPC's are interesting and well fleshed out. The locations are many and all include interesting facts and tidbits. The synopsis of each 'Episode' are full of little things it makes one feel almost like they are in the game themselves.
What I think really makes this campaign stand out however, is that it is not your standard Dresden Files Campaign. The standard Dresden Files Universe has wonderfully been meshed with Highlander, Buffy the Vampire Slayer, Percy Jackson, and others, into a wonderful tapestry with something for everyone.
Also, as of today, it has reached 75 Favorites, which demonstrates that many people here share my enthusiasm for this wonderful campaign.
So, I happily submit "Shadows Over New York":http://www.obsidianportal.com/campaigns/shadows-over-new-york for June's Campaign of the Month
