Runebound does an awesome job of making you feel like you are playing an RPG campaign in a short amount of time.
Now that Dungeonquest is also set Terrinoth, I think it could be linked via a variant to provide dungeoncrawling that Runebound lacks!
Linking the two should be really easy, much easier than linking Runebound to the ultra-lengthy Descent.
I can't wait to see the variants that will spring up for this very idea!!!
