I reinstalled Fallout 4 on PC after watching the show, but then spent more time updating mods than I did actually playing it. I never actually finished the main quest the first time around, despite putting in about 260 hours. As is often the case, it's all about the side quests!
Every time I consider going back to New Vegas, I similarly spend a ton of time installing mods, and then stop playing after like 20 minutes. Even with the mods, I just can't handle the outdated look and feel of it. (And, IIRC--like many games developed and/or published by Bethesda in the last 15+ years--the look/feel/gameplay of New Vegas felt outdated even when it was released.) That's not really a knock on it, though. I did get plenty of enjoyment out of it at the time. It's got more of that "Zany Fallout!" feel that a lot of fans (particularly fans of Fallout 2) really, REALLY love.
EDIT: I think if I do end up going back to Fallout 4, I'll just try the VR version again for a slightly different experience. Last time I tried the VR version, though, it was a busted mess that even mods couldn't fix.
ANOTHER EDIT: I forgot to mention my favorite Fallout story. When Fallout 3 came out, I was super pumped for it and pre-purchased it at the Best Buy in Columbia Heights. The morning of release, on my way to work, I stopped at the store to pick up my copy. The Special Edition version with the lunch box and the bobblehead and such. (Still have them!) A few minutes later, I was sitting on a bench at Columbia Heights Metro waiting for a train, and some dude sat next to me. He had his own Fallout 3 Special Edition lunch box. He looked at me, then looked at my lunch box, and just said, "You too, huh?"
