New Vegas was the better RPG, but Fallout 3 was more fun, and it’s a shame that New Vegas came after. They saw what worked and what didn’t in 3, and made their game after. Technically New Vegas was built on top of 3, but I’m not talking about that. I mean, it doesn’t matter for what we’re talking about, beyond that they didn’t have to build a whole game engine from the ground up, they just did the equivalent of Enderal and built a total conversion mod on top of Fallout 3.

Specifically, Fallout 3 had the fun guns like the Railway Rifle and the Dart Gun, and New Vegas had packs of nearly-unbeatable Deathclaws. Fallout 3 also had Three Dog.

Other than that, New Vegas was better.
