I have played it.
It's very simple and quick. Suitable for playing with children.
From what I can remember it's very simple trick taking mechanics (have to play in suit, highest wins) with a few special cards. It's a team game with the villain team being two players, and the heroes are three players (It works best at 5 and 3 players to maintain this balance - although it has rules for 2 and 4 as well).
I don't remember much about the good team, but for the villians one person is the dragon and gets some extra dragon themed powers. The other villian is an orc warboss. He's quite interesting because his goal is to get the dragon more tricks rather than winning himself.
However it's not (for me) very interesting. I would play it with kids, it might be a way to move from regular card games to a bit more meaty games (Introducing special powers and things like that) for adults.
I think anyone that really enjoys the lord of the rings card game will find it very simple and not able to hold your interest for long.
