The rules in the d20 system are largely really good (version 3.5, of course). But some things I would prefer to be a bit more realistic. I am a big proponent of realism in my games (as much as is reasonably attainable in fantasy settings, anyway). Sometimes I get an idea, or something bugs me about how things currently work. That’s why I tinker with the rules. Some of my ideas are good ones, and those you are welcome to borrow from me, and probably a lot of them add lots of unnecessary complication.
Anyway, that’s a brief explanation of why I tinker with the rules, and this blog will be about those rules and the thoughts behind my customization. I hope you find some of this useful. Thanks!
