Great idea!
I'm playing the 1 player version with Dain, Gloin and Bifur.
1. Passage Through Mirkwood: quite fast and easy, specially since I play Gleowine first turn to draw extra cards. 1-0
2. Journey Down the Anduin: 27 starting threat is a good amount to deal with Hill Troll, specially if you play Gandalf just in time. Later I spent a few turns crossing the river (too many sites in play), but it was good enough to enter Lorien (a dwarf host entering Lorien! hehe). 2-0
3. Escape from Dol Goldur: I guess I could play a hundred games with no chance of win this scenario. Anyway, this time Bifur was imprisoned, so no green resources, so end of story. 2-1
4. Hunt for Gollum: an interesting and close game. I had collected two clues when I was facing a 1-wound left orc and some crebain. I was thinking about not defending the orc, but finally I play a Longbeard Slayer with Sneak Attack, slaying him. Then I discarded his shadow card, and it was Hunters from Mordor! Its shadow effect would have killed both Bifur and Gloin, since they were already wounded. So I said no more risk!, and I managed to defend every other attack through the end of the game. 3-1
5.Conflict at the Carrock: long game. First I have to deal with some sites that prevent me to reach the Carrock. When I make it, threat is over 34 but I play a sneaky Gandalf to reduce it. Then I can face one troll at a time, which makes thing easier. 4-1
To be continued…
