Two more ideas:ironregime said:Wow, thanks for all the great ideas and feedback! I'm interested in the "item levels" from Magic Item Compendium. That sounds like it might really help.
I was hoping that I could be lazy and find some resources already created, but maybe I'll just have to write up the conversions myself and present them here as variants, with as much forethought and guidance as possible. Then other GMs can apply them to published adventures and avoid having players roll their eyes when a half-black dragon/minotaur shows up swinging a +2 spiked chain (bonus points if you can figure out which adventure that encounter is from).

NilesB said:Modify the D&D rulesset until it fits your preconceptions. This has no advantages over the other options, is a lot of work will create huge balance problems and renders it almost impossible to solicit player without false advertising. I do not recommend this course of action at all.
