This is a stand-alone game for 2 to 4 players. It is NOT a collectible set. Every box includes a rulebook and the same 100 cards. Praise "Bob"! No collecting!
The rules are a slightly simplified version of INWO. If you already play INWO, you will find SubGenius a very useful tool to conver... err, to introduce your friends to the game.
All the cards in this box can be used in standard INWO and cards from other INWO sets can be added to a SubGenius game.
