8. Fallout 3
The Fallout series puts a unique spin on the RPG formula, swapping out wands and magic for guns and radiation and placing emphasis on survival. Fallout 3 was perhaps the best execution of this theme, with players battling a remnant of pre-War era military and traversing the ruins of Washington D.C., adding an additional layer of horror and intrigue to an already fascinating game.
While RPGs can become repetitive and stale in their shared elements, Fallout 3 was able to take the D&D mechanics at the core of the genre and put them in a completely new context, challenging it as a whole. Its beloved legacy as a science fiction FPSRPG has been earned.
