Fallout 3 is the most interesting in the franchise because of all of it's problems.
Fallout 1 & 2 are good games.
new vegas is the best fallout game ever.
fallout 4 has the best gameplay.
fallout 76 is just kind of meh.
Fallout 3 is the worst because of the way that it adapts everything is done terribly, the story makes no sense,& the characters are boring.
