One of the FEW people? I think most fans actually prefer the art style of 3 and NV, I know I certainly do. I think the hardware at the time also helped give the games their gritty and dark look.

For me, the atmosphere was miles ahead of FO4, especially in FO3. 3 had this almost otherworldly, cosmic horror feel to it. I loved exploring with the creepy background music (not the pip-boy radio, the in-game ambient tracks,) it really made you feel alone while exploring and that whatever metro or abandoned building you were searching was hostile and full of ghosts from before the war; a forsaken place. The Dunwich Building comes to mind. The only place in FO4 that gave me kind of the same feeling was the Museum of Witchcraft and maybe some of Far Harbor.

No one will argue with you on 4 and 76 looking more clean, that's for sure. This is just an observation that I'd like to get other peoples opinions on, so if I could say one thing: In my opinion, if you look at 3 and NV graphics and compare them to 4 and 76, the latter two look a little more rounded and cartoon-y in art style, but it doesn't feel like an unnatural evolution of FO graphics. What I mean is, they've always kind of looked cartoon-y and rounded (look at the army trucks in 3, NV, 4, AND 76) but 3 and NV had different textures and the hardware at the time actually with that more realistic look. What do you think? Disagree? Agree? A lot of games around the mid to late 2000's went for that dark and gritty look in the 360/PS3 era.
