I'm not a very active gamer, and Fallout 4 was the only one I ever played. I got to the end basically, but no faction really seemed like a good choice so I took a break before starting down the final path with anyone. Years later, still haven't ever gotten around to it.
Love the whole Fallout universe lore though, and I probably watched more hours of gameplay and lore videos on all the games than I spent playing FO4. I at least got that out of giving it a go.
