Legend
As further evidence, my I enter Knights of the Old Republic? This uses a D20 based ruleset (although I don't know if it was licenced at the time). It has D&Ds ability scores, with the same range and bonus system, classes levels, hp, sneak attack D6's etc.I don't know of any evidence that WotC has failed to protect their trademarks since they revoked the D20 system licence.
You can still legally buy KotOR.
