I got a chance to play Legend of Dragonholt last night up through the To New Roads adventure and the first couple of encounters in Dragonholt village.
It had some great and familiar references that Runewars minis players will be familiar with and was a great way to get more immersed into the feel of Terrinoth. It didn't add a ton to the lore but already the sense of intrigue within the Baronies is coming out and gives a better perspective about what reasons might justify Daqan forces fighting against each other.
It would still be great to get more info on how the regions of Terrinoth connect together, but for a Runewars player, it was a pretty satisfying way to make the world feel more personal.
Also, I should say that the game play was top notch and the game components extraordinary and well thought out. It was my buddy's copy so I didn't have a good feel for what was in the box, so I kept being pleasantly surprised when an encounter ended with the players actually getting a real life artifact mentioned in the game. The encounter says you get a map, and there in the box is a map. You receive a letter, and there in the box is a letter for you to pull out and read. It was very cool and I'm looking forward to the next session.
