Fallout NV had a superior narrative and more complex characters. The writing was superb and often times hilarious. Quests were much more engaging and thought-provoking and could be resolved in novel ways and didnt fall into the WoW trap of go here, kill baddie, collect reward. The choices were also non binary. Decisions in Fallout 3 often had you pick between a selfless saint or a psychopathic, mustache-twirling dick, while NV offered shades of grey, similar to the Witcher 3. Also like the Witcher 3, when you made decisions, there were actual changes in the game world and the consequences were often unexpected. And the DLC's foe NV were amazing, especially the sci-fi themed one.

To be fair, Fallout 3 had a more immersive environment and atmosphere. It captured the setting and feeling of a post apocalyptic world. You dont feel as compelled to follow the game's questline... exploring the world was more satisfying. Bethesda and Rockstar have a penchant for making games where you can have so much fund just walking around.

I often times wish that a colloaborarive rpg between comapnies could be made. Obsidian would do quest design, CD Project Red would do the writing, Bioware would do the voice acting and character design, FromSoftware would do the world-building map design and lore, Platinum games is responsible for gameplay, Square Enix would provide the music, Naughty Dog handles graphics and motion capture, Blizzard would do the QA, Bethesda would do the mod kit, and Valve would be the publisher....
