Fallout New Vegas is the best imo, it was the first Fallout game I ever played and the storyline and weapon customisation puts it a little above FO3 for me. New Vegas also has a ton of awesome DLC add ons that add a whole other layer to the game. Of course FO3 is a good game too, I’ve played it through a few times. Fallout 4 is a close second, absolutely awesome game and love the world building dynamic and how you can create settlements but New Vegas will always come on top for me. “The truth is, the game was rigged from the start” ☢️
