But there's an enormous amount of satisfaction to be gained from dreaming up your own world with its own (reasonably) self-consistent rules and logic, and then using those rules and logic in creating the game scenario. But it is hard work.Also, playing someone else's game can be fascinating - they can be more than straight dungeon bashes. Part of the challenge can be to try and work out what hidden rules the DM has devised for his game. If you can do that, you gain a huge insight into who your real enemy is, because in a really complicated game it's not necessarily obvious. That can give your brains a real work-out. *evil grin* I played a series of games some years ago where the party was basically a bunch of detectives trying to find the perpetrator(s) of a series of Jack the Ripper type murders and the reasons for them. At least, that's how it started. By the time the games ended, we were dealing with drug trafficking, high-level corruption, covert vampirism, and a subversion attempt by a neighbouring state. And having "cleaned house," the party members were declared persona non grata - basically they knew where too many of the bodies were buried, and the powers that be weren't comfortable having them around. *TANJ!*
