Conversely, not acknowledging history or player involvement is what happened in Fallout 4 where the Lone Wanderer's actions from 3 seem to not have any effect on the Capital Wasteland and the story mostly ignores his actions (except for his one act of defeating the Enclave but that probably would have happened even without the Lone Wanderer's presence since the Enclave were rather bone-headed in their approach).
I really wish they had included more Fallout 3 lore. It wouldn't have taken much to make me happy.
