Raapys, I'm disappoint, son. Not only are you foaming at the mouth along with others but you are using bullshit to try and back up your position. While I don't know every crook and nanny of MW's system, I knew it had to be MW or something completely different the moment I saw "to hit" in your list. I mean, To-Hit in Oblivion?, WTF man
I have one question for you: have you even played Oblivion?
In Oblivion,
Strength:
Encumbrance (maximum weight that can be carried) = Strength × 5
Damage dealt with a melee weapon (see The Complete Damage Formula)
Fatigue = Strength + Agility + Endurance + Willpower
Endurance:
Fatigue = Endurance + Agility +Strength + Willpower (NPCs and player)
Base health = Endurance × 2 (player only)
Health increase on leveling = Endurance ÷ 10 (player only)
Agility:
Chance to avoid being 'staggered' by enemy attacks.
Damage delivered by bows (see The Complete Damage Formula).
Fatigue = Agility + Endurance + Strength + Willpower
Intelligence:
Base Magicka = (Intelligence × 2) + racial and birthsign bonuses
Willpower:
Regeneration rate of Magicka (see below).
Fatigue = Willpower + Agility + Endurance + Strength
Personality:
To more easily obtain meaningful information from NPCs.
To obtain better prices from merchants through haggling.
To avoid combat more often. Fewer aggressive beings will attack you and more will accept yields.
Speed:
Speed of travel (including fast travel)
The length of your jumps.
I'm looking at that list, thinking of individual skills in the game and how they interacted with the attributes and... I realise nothing of value was lost. Skyrim takes a lot of shortcuts where Oblivion's layering of attributes and skills are repetitive without much complimentary interaction. There isn't place for nuanced builds like a "hulking brute" or a "deadly sword master" or whatever because much of the action is already dependent on player skill and there are definitive division like how only Strength affects melee damage and Agility, bow damage. It wasn't for nothing that people could finish the game as a level 1 character. Most of the stuff in the character system simply didn't matter. Oblivion only gave you the illusion of "building a character" when your character wasn't worth shit. And neither game has any depth to the utilisation of its content (eg. clever use of attributes and skills in quests outside their main functions).
So Skyrim saves us a lot of illusionary time-waste character building and replaces it with direct, to-the-point choices. And it does what it does far better than what Oblivion does with what it does.
Does it make Skyrim a good RPG? No, it's still a shit RPG. "B-B-But why can't they make a good rpg, why do they have to get rid of everything that's goo? bwaaaa". It's fucking Bethesda FFS, what were you expecting? Should we cut it slack just because it looks pretty and can actually be fun to play? No. But don't come here with dogmatic bullshit about how it's not an RPG (yeah, you too VD, fuck you too) or how it's worse than Oblivion just because it lacks (or has vastly reduced) a particular layer of abstraction that you think is the core of RPGs without without thinking it through.
