There's a commercial game similar to this called Flux. It's not as free-form (there are cards with rule changes pre-printed on them), but it is easier to play with a group of new users.
One of the primary results--obvious to programmers but perhaps not obvious to the general public--is how easy it is for rules to interact in unexpected ways, often producing ambiguous gameplay which may go unnoticed by players for significant lengths of time.
