Kind of playing off the thread from last year, 'Always Available Flex', but was thinking a Zoo would be cool.
However, it wouldn't have combat at all BUT afford Scholarship/Appraisal training maybe. Basically Raven's Court, but with critters.
Allow players to appraise and recall the critters in each room, or maybe gain scholarship from studying the little informative plaques in front of each cage. Divide it into areas either on locale (alpine critters, desert critters) or type (Here in the canine room you have black leucros, blood wolves, and a crazed madman who refuses to leave, etc.) or level (passing through the silverfish and rat exhibit we come to the trollkin and boggle pen. Awwww).
Plus the eventual invasions from 'OHNOSOMEONEOPENEDALLTHECAGES!PANDEMONIUM!' would be...um...fun.
And the side benefit of being able to go somewhere - safely - and find out that yeah, maybe I'm not ready for 'x' critter quite yet. Admittedly some of the most fun I've had was going exploring somewhere and getting horribly in over my head. But anyways, just an idea.
