My oldest daughter (13) loves Descent, but her younger siblings (9 & 10), despite starting the game enthusiastically, poop out after an hour. They have no problem with our "quest" games HeroQuest, DungeonQuest or DragonQuest. But the minutiae of Descent seems to wear them down, so I'd like to simplify things by finding out if there are any details that can be taken out without derailing the game altogether.
Sometimes we take out facets of game play to make it simpler and faster for them; i.e. we don't use hero order tokens very often, and we'll take out all but 2 or 3 spawn cards; we don't even pay much attention to conquest tokens, because they don't really care about winning or losing.
So I'm wondering if anyone has ever made any house rules or house omissions to make the game easier and faster for younger players.
