Vegas was but a "poor man's F3". Seriously, the long, tedious hours spend running around a barren wasteland without any noteworthy combat . Besides a few cool vaults this game seriously lacked well-made combat scenarios.
You're getting your games mixed, Fallout 3 was trash combat randomly spawned and level scaled, NV's encounters were hand placed and your sense of scale is blatantly wrong. I regularly fuck around with the geck in both games and I could list Fallout 3's shit encounters on one hand, New Vegas not only had more but they were higher quality and required more planning. Besides that, even if 3 had great encounters, the combat, weapons, and systems in that game were so mind numbingly awful that it wouldn't make a difference.
Also, the DLC for Vegas SUCKED. Seriously, I do not know what all the hype was about. Old Man Blues was the only half-way decent one but it was BORING AS HELL
Obvious troll is obvious, but still, Poe's law amirite? There's a decent chance that you really are this delusional. OWB has exactly the kind of trash combat that 3 did, and was filled with pointless nooks and crannies filled with shit, it was like Fallout 3 but not made by retards. It wasn't my favourite, but it was better than Beth's efforts.
While Vegas was great (spend hundreds of hours on that aswell), one cannot objectively deny the fact that it was less detailed, less content-rich and had lower production values than F3 (not to mention that the game was a buggy mess).
One can, in fact, deny that, in fact we can objectively say the exact opposite. If you had the brains to reference the wiki, you'd realize that New Vegas has more content in every aspect. More perks, more locations, enemies, characters , quests, weapons, traits, more voice actors, more dialogue, and leagues better voice cast than any other title in the Fallout series. It's scale, content, and production values are unrivalled by any Fallout title(Least of all that lifeless empty oblivion mod FO3), it had big names attached and was crafted by a massive studio,
it had less bugs than 3 and the devs actually cared enough to not only patch it better than Bethesda did for their fuck up but even modded it to improve the experience long after it's release and the release of the DLCs. Like many other fans you must have a nostalgia boner for that steaming turd FO3, enjoy your coprophilia, but don't try to imply Bethesda deserves credit for anything. Their contributions to the series and it's lore can be summed up as: Mudcrabs, 3dog, and Gamebryo.
