risk is a fun game, but i think
Settlers of Catan is better at every aspect of the game:
Resource Management
Strategic Initial Placement
Strategic Expansion of Empire
Interaction between Players
Card Usage
Skill:Luck Ratio
Average Time to Play
Replayability
plus, the game board changes every time you play the game, so you have to change strategies every game as opposed to owning north america vs south america vs australia vs africa vs europe vs asia always being the same
