Advice on randomizing the game
The trend in GMing since the early 90's has been to plan complex storylines and prepare for anything your players can throw at you at the table. This has also been my modus operandi.
But I'm interested in bring the game back to it's more "primitive", "game-y" roots. As GM/DM/Referee, I'm looking for more ways to randomize my game and increase my own improvization, so that even I will not have any idea where the game is going when we gather at the game table.
Yet, at the same time, I don't want the game to be so random that it collapses into farce.
I'm looking for suggestions on how to add randomness to the game without losing all control of it.
For example, one idea I had was to produce a deck of NPC cards. These are pre-generated NPCs with some background details and motivations, but no established point of entry into my game world. Then, whenever a PC enters a public space or starts a conversation with an NPC, I draw from the deck. Depending on who I draw, it may alter the course of the game or have no immediate impact. The point is that I am no longer leading on the players.
Ideally, I'd like to expand this concept to create random dungeons, locations, and events, but ones that still make some logical sense. I'd love to have a random chart that determines things like weather conditions, but takes into account the seasons and the environment.
I want to bring dice back to the game in a big way. I'd even like to reveal my matrix to the players, so they know that I am leaving things up to fate.
Does anyone run games like this? Does anyone have any advice? I'm I crazy?
