I think what pushed people back was the amount of rules. There were so many details and exceptions and conflictive rules that was hard to organise games.
Apart of that, good news, I convinced my other half last night to try your game and my mutant gang, the Blistered Rats faced the Plutonium Chainsaws, his head hunters. We had a few squirmises mainly around his casino, wich changed of owners a couple of times. Eventually, the Blistered Rats ran out of money and weapons and ended up going a bit too often to the wasteland where my last surviving mutant was devoured by a bigger mutant. XDDD
We had good fun and we agreed the game would be funnier with more players. How many can play this?
