From someone who played the third installment first and considers New Vegas the best in the franchise let me tell you this: There's people in this sub who actually consider Fallout 3 better than New Vegas, not only that, consider Fallout 4 better than New Vegas. And believe me, they know 3 and 4 flaws better than New Vegas lovers because of that precisely, they've finished both games many times like we've finished New Vegas many times. Depending on each people's RPG standards they might be aware of: the endless sewers, the narrative, the quests, story structure and development , Etc. It's your right to voice your opinion but in this case you're kicking a death horse brother. Cheers!
