I thought it was in his sig, but no. I can't find it... hopefully I'm remembering at least the right person.
The concept of the game was to stay as OPM Ulm, convert to a heresy, force-convert every catholic nation to it, then go back to being catholic and control the curia. I don't think it was especially detailed so it might not have been a full-fledged AAR.

If you like inconsistancy, spelling errors and insights into game mechanics, that's the thread for you. Ulm was a fun game because it was a way to completly ignore the infamy mechanic of EU3. Despite playing a mod, everything there could have been done in vanilla.
