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 one 10-comment thread per month, slice o' pie.

We have a test drive up if it strikes your fancy! Any of your list would be welcome; I would particularly be interested in seeing Auron, and I know there're some variant-Trek-canons people working on apps.
