I won't be playing Fallout 4 anytime soon, but I realized while watching other people live stream it, I never actually got around to finishing Fallout 3 -- or really starting New Vegas, for that matter. My copy of FO3 is so old, WIndows 10 refuses to run it, but luckily, the modding community exists to come to the rescue. There's an absolutely incredible mod called Tale of Two Wastelands, which ports all of FO3's content into the New Vegas engine (which is optimized to work on late Windows OSs.) So, now I'm neck deep in the Capital City Wasteland, after taking about a five-year hiatus, and I'm intent on getting through it, all its add-on content, and then doing the same for New Vegas, all in the same playthrough!
I'm actually pretty surprised at how nostalgic I felt walking back into Megaton again after so long away.
Here's my guy, Warwick, just taking some time out for a swing.
For anyone interested, Tale of Two Wastelands can be found

I've never really considered Fallout 3 or NV to be FPS. I mean, yeah, technically, you're in first-person, and you're shooting, but the mechanics aren't really FPS mechanics. They're more RPG than shooter, to be sure, what with the importance of the VATS system to gameplay, and the fact that your stats have a major effect on whether the bullets you're firing actually hit your target. With a low gun skill, you can shoot raiders point-blank in the chest with a shotgun, and have it do nothing.
After putting over 20 hours in on FO3/NV over the last three days, I'd definitely say it's worth at least giving them a try. New Vegas is especially recommended for you if you love FO 1&2. It's the spiritual sequel to those particular games, while FO3 and FO4, taking place in the Eastern U.S., are more like franchise expansions.
Anyway, the last time I fully completed a BethSoft RPG was Morrowind, and I did that almost ten years ago. I've made a sort of unofficial 2016 resolution to actually complete the games that have come since, instead of spending hundreds of hours modding the things to death and otherwise futzing around, which is what I've done since Oblivion came out. I've got several hundred hours of just the official content ahead of me, so I expect I'll be playing these things for a long while.
