I mean, I love NV and think it’s by far the best 3D Fallout, but it’s also got a ton of performance and bug issues. Partly due to the engine they were working with and the insane development cycle, but still. The game isn’t without issues. It’s famously unstable and buggy if played without mods. I also think it needs mentioning that a lot of the assets look out of place, because they are. The game had such a short development cycle that a lot of them are just reused FO3 assets.

I love it, but there is a reason so many people recommend something like the Viva New Vegas modlist even for a first playthrough.
