I was re-reading the thread about subscriptions and new content for Ars Magica 5e (especially, this post). Have you (Atlas) made any decisions?
I would be interested in new content for Ars Magica, even if in small doses. Did you consider the Feng Shui model successful?
I would like to second the question as someone who has a definite interest in more Ars Magicka content.
We have a BIG Ars Magica project in process. We're not far enough along to announce it yet, but we'll be doing a Kickstarter for it in good time. Unfortunately, we're suffering from our success with Planegea, and are just now able to focus on other projects now that that's at press.
