But if you want a better game, FO:3 is it.
But it isn't a better game by fact, it's subjective.
And not everyone got a load of glitches and bugs with New Vegas, for me it has run smoothly.
You know when a texture for some reason stretches to the horizon if you look at a certain direction? That has never happened for me in New Vegas and happened all the time in Fallout 3. Could become really annoying.
In Fallout 3 we also had the bugs for the perks in Point Lookout and the bug that causes the Steelyard roof to become... "Not there", the texture is there but if you walk on top of the roof then you fall through it, thanks to Point Lookout.
I also remember flying charred corpses spazzing out in the sky and the game freezing up on me when entering Point Lookout of finishing the Vanilla game.
So Fallout 3 being a better game simply cause New Vegas has glitches and bugs? Nope.
Fallout 3 is not a better game by fact.
Both games have a severe amount of bugs in them, some are just lucky enough to never experience one, while others get the slap-in-the-face package.
Fallout 3 is a themepark, a lulz game, a sightseeing tour, a splatter simulator for dumb fun.
And there's nothing wrong with that, I can enjoy such games too, I enjoyed that for 800 hours in Fallout 3.
But New Vegas is more along my lines, it's coherent, consistent, has good writing, has lots of RPG choices and tons of AnC.
Doesn't make either of the two games "better".
Though New Vegas is the better "Fallout" game.
I don't see why you would have liked Bethesda to do New Vegas though.
If they had then Powder Gangers, Great Khans, House and Caesar's Legion would not have been joinable and had to be killed on sight. Ala Fallout 3 Raiders.
And you'd be railroaded down the NCR goody goody two shoes quest line without being able to break free apart from at the end.
Oh and 30% of all charactes would have been set to Essential so that they can never und I mean NEVER be killed.
Just saying. Bethesda would do better? Fat chance.
