Notice ole chris said praised by CRITICS.
The game itself was a buggy unplayable mess that you could only fix on the PC version.
To date there remain several crippling bugs that are very common on the console versions. <- the Common part is the important bit.
Oblivion, Fallout 3 and Skyrim all had bugs but Bethesda didn't leave them broken they eventually fixed the worst ones.
Not to mention NV was more of a 'new take' on a Fallout game, despite having a handful of throw-backs to the old games, it played nothing like them. It looked nothing like them. You weren't even part of a vault. You were a mailman!
The difficulty was artificially inflated by placing super high level enemies near starting areas; enforcing linearity.
The exploration was boring. The world was boring. A lot of the guns were recycles; in fact most of the textures, animations, etc. Were BETHESDA'S.
I just think they did a horrible job, and to this day I do not enjoy playing NV; but I don't claim FO3 is perfect.
I will say this in NV favor: they did a pretty decent job with the dialogue.... however, Bethesda proved they can "blow them out of the water" in that regard as well by having a massive cast of interesting characters and voice work in their latest game Skyrim.
I really see no real benefit to 'some of the old guys' working on a new Fallout; they've proven they don't know what they're doing and that they can't translate their old 2d games into the 3d game era. They even had most of the work done for them by Bethesda; The graphics, the animations, the weapon types, the skill and level up system, the VATS system, everything.
NV is a glorified buggy as hell fan-patch that cost $59.99 new.
-_- and yet people will love their games simply from trust, because their old games were so good. But the thing to remember is you don't have the ENTIRE team from the old games having worked on NV, in fact I'd say you have none of the truly talented ones working on it... Usually, the real heroes go un-sung, and the big-wigs take all the credit, and I believe this to be the case in this situation. People give credit to the big popular names but all the little people who worked on the old games? Pft, doesn't matter... that ONE or TWO guys can produce all the content we loved from the old games... BY THEMSELVES! Because they totally made those old games by themselves, right?
