To be fair, I never had any of the bugs people mentioned in either Oblivion or Skyrim (apart from Esbern poping up everytime I fast travel... but that might be something I broke on my own...) Maybe I'm just lucky, but at the end of the day I experianced a heck of a lot more trouble trying to play New Vegas than I have Bethesda games.
No, you have. In that list were Oblivion's unique weapons that were never fixed (example: Molag Bal's mace) and Blood on the ice.
After all the patches, Bethesda never fixed several leveled items in Oblivion that either leveled incorrectly or their function didn't work at all.
Also on the list is the quest "Blood on the Ice," which, if you can complete without a glitch, I'd love to see a video walkthrough of it. I'm afraid to touch the damned thing until they patch it.
Why reply to blind ignorance with anything but the same?
And how exactly am I ignorant?
Do you even know what ignorance means?
Ignorance means the lack of knowledge, which makes literally no sense in this discussion since I'm citing both examples from New Vegas and Skyrim. How am I lacking knowledge on either?
After a few debates, it's all just down to personal preference. It is also down to the location itself FO3 and NV are set in real locations; FO3 in DC and NV in Vegas. Of course a city is going to have metro tunnels. It would be less believable if it had none or just a few. But hey, FO3 being unbelievable is your opinion, who am I to tell you that what you feel is wrong

Count again. Just because there are three main archetypes, doesn't mean you can't mix things up. You are not shoehorned into a playstyle in Skyrim.
FO3's world realistic?
Please excuse me while I blow your argument out of the water. Ahem:
Little Lamplight
There you go. Now that we've got that taken care of....
As for the three archetypes....yes you can mix magic, combat and stealth as you please, but tell me....How does your mace character play any different from your sword character? How does your Light armor character play any different from your heavy armor character? How does your two handed character play any different from your one handed character? How do ANY of your characters that utilize stealth kill enemies differently?
That's my point, the differences are minimal. Absolutely minimal. If you want to make a list of "different ways to approach the enemy" then your list for Skyrim will probably have ~3 different ways, with any other ways being a mix of the first three (for example, instead of "charge in and brawl" or "summon a bodyguard while frenzying half the enemies" it becomes "summon a bodyguard then charge in").
New Vegas? What different builds approach situations differently? Just to name a few:
-Shotgun users ("juggle" enemies in first-person, enemy DT is an issue)
-Melee users ("juggle" enemies, exploit VATS in between and utilizing cover is a must)
-Unarmed users (utilize VATS to stun enemies, utilizing cover to close the gap is a must)
-Snipers (abuse sneak, aim, don't screw up, Fast Shot is optimal)
-Automatic weapons (proper ammo type is often key, Trigger Discipline is optimal)
-Cowboy weaponry (Cowboy perk ideal, Hand Loader ideal, high agility and/or Rapid Reload is ideal, afterwards sneaking works best)
-Modern weaponry (Grunt is ideal)
-Explosives (lay mines, get Heave Ho! so Grenade launchers have "perfect" aim, mind your distance from the enemy, try to group enemies)
-Energy weapons without meltdown (Get high luck, high repair, perks to manage repairs and carrying weight are ideal)
-Energy Weapons with meltdown (Same as above but mind your distance from the enemy, try to group enemies)
-Automatic energy weapons (get ED-E and get all his Lonesome Road perks, get Laser Commander)
Just a few, but really,
the key difference? Your character can and can't do certain things. For example a character with Heave Ho! is simply going to have a far easier time aiming with grenade launchers than a character without it. Your character with Trigger Discipline is going to use automatic weapons better than a character without it. Your character with Better Criticals and the end-game perk (you can only pick one of three) Lucky to be Alive is going to be a god with the weapon "Old Glory," but your character with Heavy Handed will think Old Glory is a piece of [censored].
It's impossible to be good at everything, BUT this makes each character feel unique and they truly perform, play and handle differently, so that each new character feels almost like you're playing a different game entirely. Skyrim lacks differences like this and limits them to ~3 playthroughs.
The SPECIAL and other perks will greatly change each of those. A sniper with Fast Shot is already something different from a Sniper with Trigger Discipline. An unarmed user with Heavy Handed is already quite different from an Unarmed user without it. A Melee user with low STR is already quite different from a melee user with higher STR.
With Skyrim? The only difference you'll see is magic character vs. non-magic. A magic-focused character can use all spells but has less health, a non-magic-focused character can't use all spells but has more health. That's it. Otherwise,
any character can do anything, and you certainly don't mind if one character does better damage with one handed rather than two handed, or maces instead of swords; it all plays exactly the same.
Yes Obsidian are great writers, but also smarter game designers. Here's J. Sawyer on weapon balance:
This post basically sums up
why we need balance in single player RPGS. Click the link back to this person's post and read it.
Skyrim lacks this. Whereas J. Sawyer is figuring out a way to make that pistol you get at the start of the game a viable option for the ENTIRE game, Skyrim is going "here's a steel sword. It's special qualities are UUUUUUHHHHHHHHH~.....It's weaker than Elven but stronger than iron." EVERY WEAPON FEELS THE SAME. In New Vegas, each weapon is unique. The weapon you use defines your character about as much as your character's stats.
Skyrim
doesn't even have this concept. This is a level of depth where Obsidian is playing chess, Bethesda is playing checkers.
This point alone is enough for me to think anyone who says "Skyrim has better gameplay mechanics" has no idea what the hell they're talking about and hasn't even played New Vegas. If you know of this feature of New Vegas and have experienced it and STILL think Skyrim has better gameplay mechanics, please explain why. I'd love to know.
TRy walking over the hills after you leave the first town to bypass the super long route or the cazadores in NV, invisible wall going through HALF THE MAP. Or the invisible barriers preventing you from swimming to Caesars camp, don;t tell me about open world games when you are are just basking in blind ignorance.

Props on actually finding an invisible wall that affects gameplay.
...yeah, just good job. I generally ignore the critique about invisible walls because the people who bring it up are like "OMG I can't believe this invisible wall is keeping me from getting TO THE VERY TOP OF THIS EXTREMELY STEEP HILL I WAS STRUGGLING TO CLIMB." Yeah, [censored] man. How are we supposed to enjoy the game if we're not allowed to reach the top of hills in the middle of nowhere that, visually, look like they'd be impossible to climb from the get go?
Makes me wonder how many people playing Skyrim do nothing but find little mountains and hills and spend all day jumping up the rocky sides of it, thinking it's the greatest game ever when they reach the top...
