Which came first, the phoenix or the flame?
While this game does have 3 small, reasonably priced expansions as far as cards go. They also have a couple of free, downloadable, prinatable outable expansions too.
1. Mage Generation System: Think like GURPS or something. You have a cetain amount of points and you can distribute them to make your own cutom made mage to play with with different abilities and skill levels, very cool.
2. The Landwars Expansion: CCGs meet risk. Comes with a map (shown in some of the pictures) and each game you win earns you a territory. Conquor the world to win.
3. Treasure Trove: Battles yeild new treasures (or possibly traps) fun and exciting.
These are just 3 more reasons to play an already great game.
