Nice work, thanks for putting in the effort, good reports.
I recently bought Erehwon and have enjoyed a few games of that, it has that granularity you mentioned and plays quite a lot like WHFB of old, though more streamlined, more random and loads more fun.
Still, even though my Erehwon book still has that new smell, I think I will get the Saga stuff too. Already got the rules and vikings so it's not too much of a wallet hit to get the AoM. Are the cards printed out yourself or did you buy them?
