The timing of this couldn't be better. I'm currently working on a Conan project myself, and have often wondered how Pulp Alley would handle things, especially solo - clearly it does well. I still lean a little towards Matakishi's CROM! rules (they're made for it, after all), but this has got me thinking again about trying other rules.
Your game looks stunning, by the way. Love the altar! Could you possibly provide a link to the Mierce monster? I don't especially like their website and am having trouble finding it! Thank you for the inspiration!
