Well yes, I always yield to vehicles that are already in the intersection, irrespective, again, of their turn signals. Also it is not purely true that "the first to stop is the first to go". Specific minutiae of the law differ depending on region, but generally if I am approaching a 4 way stop with the intent of turning left and another car straight across from me is already stopped and going straight then, while I am waiting for that driver to cross the intersection another vehicle arrives at the stop to my right I am still obligated to yield the intersection to the new car despite having "arrived first". Likewise, when many cars are enqueued at the intersection, turns should continue clockwise, as in most board games, without regard to who is able to zoom up and brake the quickest.
