So NONE of you are interested in actually SEEING the fruits of your labor? To you it's irrelevant that you chose to side with the NCR and defeated the Legion, or vice versa? You're not even remotely interested in walking about the Mojave and seeing the lasting affects of your choices?
No, because it would be pointless.
Sure I could witness every change in real time by myself but what point is there to it?
Everything's done, nothing to do anymore but roll through the wasteland in boredom.
Rather they work on more toybox DLC's than a pointless DLC that makes the ending pointless.
