I've heard back from Drivethru and Ars Magica doesn't meet it's standard for an entry into the ruleset list in their product classification system. Here's the email:
"Hi Timothy -
We have a few requirements for new Rule System filters:
- Minimum 30 titles published by at least three alternate publishers (i.e., not including the core rules publisher); and
- Minimum $700 USD gross dollar sales for that game system within the past year, both a) average monthly sales for the past year, and b) minimum monthly sales within the past three months."
I feel I've done all I can here. I presume we have three publishers because some of the fanzines are on there, but we don't have 30 products. I don't know how much Ars makes there.
I'm going to put up my bestiary posthaste as a freebie just to get closer to that 30.
