Probably an unpopular opinion but I like Fo4 better. It was the first Fallout game I had played and I replayed it over and over before I played any of the others. For Fo3 I couldn't get into it as much and it didn't help I was playing on ps3. It was a little short for me and the dlcs weren't as good as I anticipated. Obviously the graphics weren't the best and the whole scenery was kinda dreary (which is how it actually should be) for some reason that made it harder to zone into it. I probably need to replay it honestly. And last, I'm just plain bias on Fo4s part
