MM - Over-rated, whatever. Every opp that I ask says the game still earns. Novice players like it because they can bash the castle. Pros like to for many reasons.
RFM - Great humor, great value.
Jurassic Park - Easy to play, people remember the t-rex.
Stern's latest, so Metallica or Star Trek - Both great games with fun gameplay.
T3 - Fast gameplay, easy to understand. People like the RPG toy.
