For your consideration: The Warehouse, a panfandom game set in the Warehouse 13/Eureka universe. We're new and fairly slow-paced, so far; there's an overarching meta plot that you can join or not, and opt-in Artifact plots (we should be hitting the first of those this coming month). AC's incredibly easy (one thread, 10 comments); there is a network, but most of the action's been on the log comm so far.

We have a test drive up if it strikes your fancy! Any of yours would be welcome (I only know canon for Daine, and Sunshine by RP osmosis in another game, and I think either of them would be great to have).
