I played the base campaign with my 8 year old son. It was like playing solo, but with a feisty little helper. He is not interested in Heirs of Blood or the Coop Kits (I own). He tells me he wants a cool new expansion before playing anymore Descent.
Which expansion has the coolest monsters and heroes for kids? Which has a cool story that kids would enjoy? I am leaning towards a small box expansion that has a shorter campaign.
My son enjoys The 3 Stooges, Minecraft, Michael Jackson and Haunted Houses.
Seconding Manor of Ravens cause of the Haunted House bit. Although it isn't the one that comes with the Bard, that would be Shadow of Nerekhall. Manor comes with the Bounty Hunter & Marshall (Paladin-like class)
Storywise Manor of Ravens goes something like: 1. Old powerful mage who lived like a hermit and gathered many magical artifacts dies in his home 2. Burglars break into his manor and steal things 3. Part of the manor (Skarn) comes alive and angrily attacks anything near the area 4. The heroes have to stop Skarn before he grows too powerful
