What does the demo CD do? Can you play any sort of game on it? Or is it just a video of how to play?
Wait, you've never played it before? It's magical...
To the best of my knowledge, (from what I remember), you're given the choice between using either of the two Towers starter decks, with the three rares being fixed (I remember one of them being
Orthanc Champion), and you can set the difficulty rating for your opponent and what deck they use. Then, you simply play the game! It's like a decipher sponsored 2003 version of gemp, except it also had the lotr tcg online rolled into it, which they tried heavily to promote.
Back when I first got into lotr tcg, this thing was gold. Helped me learn the rules really quickly.
