Yeah it's as good as people say it is.

Just snip off the scenario at the end with a PDF Snipper tool and you're good to have rules to give your players when they play.

It's a bit like The Haunting in that it's clearly meant to be customized. Can't wait for the roll20 version that I hope is still coming out. You could probably run a few games with just this and some decent homebrew.

The scenario at the back has the chance to become the new "The Haunting" in all honesty.
