So, I'm interested in looking at examples of siple insanity rules for my next game.
These need to be of the old school sensibility.
I'm aware that insanity rules exist for other games, but I'm not really sure which games/examples would be worth looking reviewing.
Left to my own devices I'm thinking of using perhaps the wisdom or intelligence score as a base threshold. Characters start at zero and depending on the situation, circumstances, unwholesome things they are exposed to, a number accumulates over time leading to insanity (whatever ability score). Having said that, I'm open to alternatives.
Can anyone suggest insanity rules that I could use in an Old School D&D game?
