Recently I was asked if I had my house rules for S&W in one place, and the answer I wanted to give was "Yes. In my head."
It's not that I don't have them written down - most if not all of them have been posted and discussed here at The Tavern - I just don't have them all in a single post, let alone a downloadable document. Maybe with next week's mostly staycation I'll have a chance to rectify that.
The thing is, with me, I find it damn near impossible to run any game, especially an OSR game, as written. With nearly 35 years in the hobby, I have my own ideas of what works best. These days, with all of the OSR games available (many for free) making a mongrelization of the various rule sets is much like picking from the classic Chinese Restaurant menu - 1 from column a, 1 from column b, etc. Swords & Wizardry Complete is my baseline, but my games step far away from that baseline in actual play.
Do you use house rules in your campaigns? Just a few minor ones or a crapton of large ones? Maybe something inbetween. Do you RAW (run as written) and if so, why? If you house rule, why?
