Yes. If you liked skyrim, oblivion, morrowind you wouldnt complain about the graphics.
Fallout 3 has the most iconic plot and atmosphere.
Fallout new vegas is the best well rounded fallout game with a better joyful and humor.
As someone said, the outer worlds is releasing soon, it has the same principles of the fallout games (same creators of the NW and fallout 2)
Edit: try also mass effect triology. Even if it is more "on rail" than other games, its arguable the best RPG triology ever made.
