What it truly needs is further support, though there's little difficulty in adapting "grown-up" adventures to KCC. The rules are simple enough for kids - perhaps too simple at times. Our youngest grandson had no problems picking up Castles & Crusades' rules for players. (Mainly, just one rule.) On the other hand, this is something the five-year old and three-year old were able to enjoy, if only for a limited time.
It succeeds in its objectives, and is a very good game - kids or otherwise. If it just included a ninja cut-out miniature, the previously-mentioned 7-year old would consider it perfect!
