Fallout 1, 2 (and pre-Bethesda games)

Fallout 1 and 2 are still my favorite, followed by New Vegas.

Fallout 4 is a peace of shit plot hole mess with dumb dialogue, predefined character roles, no skills, no way to be bad, unkillable NPC's, you get the fekin power armor and a minigun in the first 20 minutes of the game and kill a deathclaw on the spot too, even though you're supposed to be a female lawyer.
