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). The AC's easy (one thread, 10 comments); you'd be the first in your canon for any of 'em, but any of your canon characters would be welcome.

We have a test drive up if it strikes your fancy!
