This is mostly first edition stuff though maybe second edition isn't that different. It's most of the stuff published for Aces & Eights minus some free, mini-supplement, and adventure PDFs.

I guess the biggest problem is that combat features using a Shot Clock, a transparent circular grid you overlay over a target silhouette so you can determine exactly where your shot hit. Reminds me of an old RPG that also used a transparent overlay with a grid.

I guess it wouldn't matter much to me since I'd run it with GURPS. In which case is there enough source material? Maybe not so I think I'll skip this bundle.
