Fallout 76 isn't really something you just play "next." Personally I play 76 casually when I don't wanna play RDR2A, or I'm thinking of a new C.A.M.P. idea. So really you can play it alongside any other video game.

Fallout 2 has the best story and quests but the pvp isn’t that good

F3 has the best map from the 3D universe

Just go the Mall in front of the Capitol and let the music « Price of honor » play

Fallout NV for the caps my friend

Fallout 3 for sure

Tale of Two Wastelands

Always heard that was incompatible with Project Nevada, and that's too many goodies to live without
