There are many Master List of 'x' floating around, which focus on various aspects of D&D and d20, such as my own
Master Psionics List, the old Crystal Keep Indices, Zook's
Full Spell List, and Captnq's very close
EVD, not to mention all the many
handbooks...
Has anyone thought to compile all of this by rules and mechanics into a Master List of Rules for D&D/d20? Would anyone have interest?
