I'm considering starting an Ars Magica game on here. Any interest? If I did, I'd be using Fourth Edition, which may be found here for free: https://secure.sjgames.com/login/login.cgi?url=http://e23.sjgames.com/downloads/e23-070729-044076-g8ugFgXQD51biIrZcjdMYTOGcWjJicId-AG0204/Ars_Magica_4th_Edition_Core_Rulebook.pdf

I'd probably tinker with the time and setting a little as well.

I love Ars Magica! But considering how lousy I am at keeping up with online games I'm going to pass.

Just out of curiosity, why aren't you using 5th Edition?

Because I don't own 5th edition...I find that to be a pretty good reason. Besides, 4th edition's free and so is available to more people.

What did they change anyway?
