Here's a set of house rules that I developed for my group. From this, I created Custom Characters.
Drawing on concepts introduced in Custom Characters and my D&D house rules, I came up with a rules-lite set of guidelines that can be used with the above documents. These are really just notes; users should be extremely familiar with a wide variety of d20 games including D&D, d20 Modern, and Mutants & Masterminds. Familiarity with the M&M Mastermind's Manual will greatly aid a potential GM as a number of concepts are drawn from it.

Yet another magic system. This time, we get rid of Vancian spell slots and spell points in favor of spellcasting based on an increasingly debilitating condition known as Mindfog: Basic d20 Fairy Tale Spellcasting
Now there are just too many magic systems. Once again, we get rid of Vancian spell slots and spell points, but this time the limitation on spellcasting comes in the form of a temporary loss of spellcasting: Basic d20 Loss-Based Spellcasting
I know this has already been done, years ago, but here's my take on separating race and class in the D&D Rules Cyclopedia.
