I thought this was going to be about paper-and-pencil RPG.
Heh. Way way back in the day, I bought the original TOS paper and pencil RPG. For my two friends I designed a killer dungeon/encounter. They took Kirk and Spock and four security guards. This encounter had several 'random party member dies, roll who bites it' traps.
Sure enough at the end, it was just Kirk and Spock.
