I totally agree with you about Skyrim, but they removed the Stats not the Skills.
And if they would have kept the Elder Scroll stats, removed the skills, the Perk trees would have done a great job replacing the skills.
They took all the stats and combined them in to your Hit Points, your Stamina, and your Mana.
There was no way to play a really smart Dragonborn or a really dumb one.
No way to play a low Charisma Dragonborn or a very Perceptive one.
Which meant the game's NPCs treated you exactly the same.
The game had no way to offer you a different option if you had an exceptionally low or high stat.
Which meant less chances to roleplay.
Yeah they dumbed it down.
Skill percentages worked great for Fallout 1 and Fallout 2.
But we don't actually use them in Speech, or Lockpick, or Science, expect to see if the skill percentage is high enough.
Most of what a Skill does effect in game is all behind the scenes now.
Perks already do some of the things that skills do.
Power Armor Training is a perk.
Demolition Expert is a perk.
Rapid Reload is a perk.
And understanding what taking the Rapid Reload perk means is easy then understanding what adding 15% to the guns skills means.
We just have the perk do what the skill did behind the scene (like reducing recoil).
Plus they are putting the Special Stats front and center where they have a direct impact on the game including persuasion, barter, and stealth.
So they move Special Stats way up and combined Skills and Perks together.
And it can be shown having a bunch of perks which cover different aspects of the skill (say automatic fire vs sniping vs pistols) means the F4 Sole Survivor is going to play and handle much more different then either the Lone Wanderer or the Courier.
And isn't that what skills are suppose to do in a roleplaying game?
Allow a character to do things that the player can't?
Provide a real difference between what the other characters and NPC can do based on what skills they have or don't have?
I think we have come out a head.
Guess we find out in 4 months.
