Fallout
It didn’t take long for players to realize they were playing something, well, special when they installed Fallout way back in 1997. Turn-based combat had been done before, and so had post-apocalyptic settings. But the game featured a design and writing aesthetic that worked incredibly well together – the rusty husks of 1950s style cars and buildings, the cobbled-together look of wastelander wardrobes, and the constant worry of radiation all combined to create one of the most defining games in the RPG genre.
