Which Fallout game should I start with?

If you're new to Fallout and want a mix of modern gameplay with strong RPG elements, starting with Fallout 3 or Fallout New Vegas is advisable. They offer accessible controls and an overarching feel of the series' themes. Beginners may find Fallout 4 to be the most user-friendly, though it compromises some of the series' traditional role-playing depth for other features.

With every installment, it continues to captivate audiences with its mix of survival, exploration, and the dark humor wrapped in layers of the series' signature retro-futuristic style.

With the promise of future titles and media adaptations like the Amazon TV show, Fallout remains a beloved universe in the gaming landscape.
