Legend
Any system which has a GM setting challenges for players to overcome but rolling dice, and thereby achieve some sort of reward seems pretty close to D&D to me in basic ethos. The above are examples of ones that do not.
There are, however games that do the first part of this, but the only reward is the success of the task itself, which seems at least non-trivially different from games driven by money and advancement. Even the traditional types of superhero games come to mind here.
