Underground Gaming

Is "Underground Game" in your opinion the right term for a political, non-commercial gaming scene? While some don't mind the term, some seem to be skeptical about it, stating that a self definition of underground is inherent inauthentic (we had, however, the uComix or various literature and press collectives using the term "Underground") or that the association with illegal activity could be a problem; these people, however, seemingly also most often disagreed to the far left political orientation of the Underground Gaming idea, and I'm not sure if those not just aren't bourgeois doubts.
