I was expecting that too… assumed the Battle of Glymmsforge to be that mini campaign…
Forge Bane had three scenarios in the box and even the Storm of Sigmar mini box had a four part (although the first three very crap) campaign to teach you the rules.
A few small battles to teach the rules and working towards a ‘full box contents’ finale would have been good. Bit crap in that respect.
I’ve built the Objective tokens box and Malign Sorcery so far, less daunting than the big box of Soul Wars. They were quite easy to assemble.
