I have played a lot more expansions since the first time I made this list. So here is an updated list of my Top 10 Board Game Expansions. Games I have not played but have heard good things about are listed with the Honorable Mentions.

10. Pizza Box Football Expansion – Lets you play with your favorite team and adds advanced offensive and defensive play selection.

9. The Settlers of Catan: Seafarers – Keeps game play the same but adds some exploration and new scenarios.

8. Epic Battlelore – adds support for up to six players

7. Legions of Darkness: Books of Magic – This expansion adds new spells, guardians and new tougher bosses.

6. Nightfall: Martial Law – more minions, more cards…more fun!

5. Defenders of the Realm Hero Expansions 1, 2 & 3 – Maybe I cheated by putting these all in one, but the new Heroes all add something different.

4. Pandemic: On the Brink – This expansion has new scenarios, new game components and new roles.

3. Race for the Galaxy: The Gathering Storm – Having goals makes this game easier and more fun to play.

2. Thunderstone: Thornwood Siege – great when added to the cards in the base set or on its own.

1. Dominion: Prosperity – Brings new life to Dominion no matter how long you’ve played the base game.
