To what extent do you or your gaming peers use and develop house rules? Are you the kind of player who builds a system from the ground up, the kind of player who endlessly tweaks an existing game system to improve its performance, or the kind of player who uses a system out of the box? How does it affect your playing style? How does it affect the balance between rules mechanics and ìpureî role-playing?
We use a number of house rules, but nowhere near as much as we did with 2nd edition.
(Amber doesn't really use rules, and we're not playing much other than D&D these days. Even starting a D&D Modern game, so will have to let you all know how that goes once it gets off the ground.)
In our current game, the biggest house rule we use is that characters get back twice their level in hit points each night, if in the care of a healer (ie, party cleric). The standard is that, but only if the character in question does full bed rest. It's better than level+1 or whatever silliness it was in 2nd edition.
We don't endlessly tweak a system - most of our gamers aren't system whores, they're there for the game, be it the experience, the social aspect, the roleplaying opportunities. So we find a system we like, and go with it. And since I'm not a system whore, that's all I really have to say on this.
