Nothing alike. Rules are way different and shot's are different. If it was me I would probably keep Avatar but I know I'm in the minority their. Maiden can be a long playing game and in a two pin collection I'd rather have one short player game with basic rules and one longer game with deeper rules.
Quoted from Heliogabalo:
I´m thinking about buying a Spiderman or an Iron Maiden...
Can you help me?
Is it for you or your family?
Family pin - Spiderman
For you - Iron Maiden
Both have some stop and go as well as good flow when you are hitting your shots but the depth of the rules of Maiden is what would push me that way.
