I will have to wait until I get home to watch TB's videos.
However, I would have to say that I am a bit disappointed with Fallout 4 though it is still a good game.
It definitely feels less of a RPG compared to Fallout 3 and that is due to a culmination of several things which includes dialog choices and the perk system rather than a numeric skill system (with perks) in FO3. But there's also the fact that weapons no longer deteriorates as you are using them. Yes, repairing armor & weapons can become a pain and in FO3 I had a bit of a habit making repairs every time something dropped to 90%, but it added to the overall RPG feel of the game. VATS was much better in FO3 because you can target weapons like focusing at a grenade while your enemy is still holding it.
I am not looking at Fallout 3 through rose tinted glasses or relying on some distant memory of the it from years gone past. I finished replaying Fallout 3 right before Fallout 4 was released. It was mostly vanilla FO3, I didn't install any mods that changed the combat system... I did not even bother with installed graphic mods either. Most of the mods I installed basically fixed some technical issues with FO3. Overall, FO3 is a much better RPG FPS game than FO4.
But that doesn't mean Fallout 4 is a bad game. The combat system is a definite improvement, I can use iron sights now and I do not use VATS as much as in Fallout 3. Not to say VATS is bad, but the updated combat system makes the game more immersive when fighting. While grenades (mini-nukes, motolov) can no longer be targeted in VATS, it's really not that big of a deal. If FO3 had FO4's combat system, then FO3 would have truly been an awesome game.
Personally, I did not have much of an opinion regarding settlement building in Fallout 4 when I first heard about. I simply thought it was an interesting concept that was probably worth checking out. At first I was a bit lukewarm about when I started building, but eventually I started to get into it. I think it's is a nice addition to the game since you can actually change landscape within the game (other than blowing up Megaton in Fallout 3). While building settlements is a nice sandbox within a sandbox it is a half baked idea that is missing what I and many a lot of basic features. Settlers cannot be renamed, there is no way to quickly determine what each settler assigned job is (if any where assigned), half the time the settlers are simply standing doing nothing. Even at night they simply stand around doing nothing even though not 10 feet away there is a simple structure with nothing but beds in it. Let's not forget auto failures if you did not personally show up at your settlement when it is under attack.
Settlements is a half-hearted feature of the game which actually needs the help of modders to improve upon this less than rudimentary game feature. I think that is the good and bad part of Bethesda's RPGs games. It's one thing to allow modders to improve upon a feature within a game, but it is an entirely different matter to rely on modders to fix lazy half implemented game features and settlements really sticks out like a sore thumb.
Overall, I am having a lot fun playing Fallout 4, but in my opinion Fallout 3 is overall superior to Fallout 4. However, that takes into consideration all the DLC that has been released for FO3. Will DLC eventually make FO4 equal to or better than FO3 in my eyes? Only time will tell...
