I'm quite certain this game will go down as my all-time fave dungeon-crawler and fave FFG game!!!
You can play this sucker solo right out of the box!!!
The game also plays really fast unlike Descent which takes 6+ hours.
I love Terrinoth, especially Runebound so this game will gel really well with that! (it covers the one aspect Runebound does not...dungeon-crawls)
Thank you Fantasy Flight Games for realizing there is a need for a fast, challenging dungeon-crawl!!!
