Lord Ghee: I ran a game like that once. I asked each of the players to tell me what they wanted to do in a game. One of them said, "I want to have a cool super-gun." One said, "I want to be invulnerable." One said, "I want to be a gangster." I said, "I want to run a pulp game." So we wound up with 1920's gangsters loot gadgets from the wreckage of a Martian shapecraft and taking the coppers to task.
