- Player Dialogue. New Vegas had great depth in dialogue options for your character. Skyrim has absolutely no variety in what your character can say, crippling countless role playing styles. Speech in NV is a useful skill because it fundamentally shaped how a quest played out. Speech in Skyrim is borderline worthless.
New Vegas dialogue and great depth? You can't possibly be serious. That was one of the reasons I gave a sh*t to Vegas.
- Handholding. Skyrim treats us like we're kindergarteners. Half of Skyrim's populations is immortal, which is annoying more than anything. Quests are unable to be failed in Skyrim. This is frustrating and lessens any sense of accomplishment from completing difficult challenges. New Vegas has almost no immortal NPCs, and quests feel important because they aren't completable if you don't have the skill.
False question in my opinion. I think there was exactly the same sense of accomplishment in Vegas. You have to be stupid to fail quests in Vegas.
- Perks and Skills. In Skyrim, skill isn't very powerful. I would estimate 90% of power is from perks, and 10% is from skill level. This effectively cripples skills in and of themselves because they don't help a lot directly. For example, one handed skill 30 and a perk is equal in power to 100 skill in one handed and no perks. New Vegas has the power at about a 50/50 split, meaning both skills and perks have power without either becoming worthless if you don't focus on both of them. Perks are just plain better in New Vegas too.
Great! You've got perks! WTF do you want more? I wish I could get crossbows and spears back!
- Scaling. New Vegas has scaling based primarily on geography. This makes the world realistic, and allows the player to fight extremely powerful opponents right from the beginning. Skyrim has scaling primarily based on level. This both dis-incentivizes leveling your character, as well as lessening believability of the world.
In practice, I don't get how geography scaling makes you fight more powerful opponents just for the heck of it. Can you?
- Companions. Skyrim has boring companions. Only a handful have semi-interesting stories to tell (like Mjoll the Lioness). Apart from being kind of boring, they lack a companion wheel to properly command them. New Vegas had a ranged/melee toggle, a stay close/stay far toggle, a "use healing" button, an angry/passive toggle, and a few other things. Skyrim has only a wait/stay and a somewhat unhelpful "do this" button. The "do this" button in Skyrim also doesn't work right half the time, because companions attack horses instead of riding them. New Vegas has companions focused on quality, and Skyrim focuses on quantity. I believe quality should come before quantity when it comes to companions.
I am trying to remember about a quality companion in Vegas.
- Reputation System. Skyrim doesn't have one, either viewable in a menu or behind the scenes. Stormcloaks treat you virtually identical whether you are a Legate or a Stormcloak General. Same with the Empire. New Vegas had factions that would change how they treated you based on your interactions with them. This caused choices you made to have impact, and made the game world feel more alive. It also helped role playing, because it made your alliances relevant to the character you were trying to role play as.
You are completely right here, and I see this as a flaw in Skyrim.
