Hi Gregg - yes, I guess we Europeans are fairly active in the gaming space ;) [UK based myself]
Have started my first campaign - 5 runs in and have had a few nice moments, inc. using a card that the Knowble was immune to, so I can fill my "effort" whilst the other cards made the goal, discarding more than effort required cards to make the goal, rather than failing -- not "efficient" but success matters longer term..
Have completed 3 passive abilities - went with Double Edged Aces, Pathefinder and Conduit [in that order] - flexibility and information probably key?
As both a math and poker guy - this is a really nice blend of game engine concepts :) I have looked around and seen you are planning on "challenge mode" content - look forward to what that is going to be - in the meantime, I think I'll run a few 25(?) run campaigns and look for best scores etc
