Yet you can easily replace them with Health, Magicka, Stamina, and a skill perk system.
Strength merged with Weapon Skills One Handed, Two Handed
Intelligence is merged with Magicka
Willpower is merged with Stamina
Agility is merged with Archery/Stamina
Speed is probably at a set amount like FO3
Endurance is merged with Health
Personality can be merged with Speechcraft
Luck is useless and can merged wtih other perks
The attributes can easily be replaced and aren't as important as the skills that you use.
I am very sorry, that is not realistic or logical in the slightest. What they have done is not a
mathematical
simplification but a crude simplification of human existence and here's how:
You play this guy: http://elderscrolls.com/skyrim/media/screenshots/dragon-approach/ Obviously a bit above average in the muscles department versus the average human/bipedal of the TES world. I'm thinking all that hard work did not give him time to study say - mathematics and astrology like say more studious or mentally inclined individuals.
I'm playing Mitzy the Barmaid: http://elderscrolls.com/skyrim/media/screenshots/tavern/ Shes obviously not as muscular as mr horned helmet. But i'm willing to bet she has areas that she might be more likely to be better at than mr. horned helmet - natural areas mind you - not skills. Basic human interaction - say.. charisma.. perhaps?
In the game- they both would have the exact same intelligence (so everyone in the world has a 100 IQ - ) same strength (so person studying ancient languages at say church sponsored school versus a trapper in skyrim have exact same - everyone in world is exactly alike.
Well you might say - archery replaces agility. No : Mitzy has never picked up a weapon but she has danced out of the way of greasy hand of drunken patrons. Using a bow does NOT make mr horned helmet any better at the balance beam. Well you might say - endurance is the same as health. No - swinging swords make mr. horned helmets arms quite thick (but no stronger than little mitzy apparently) making him quite top heavy. Whereas mitzy might used to slinging casks of mead on her back or head (say like in many third world countries still do today - women sadly acting as pack animals) so mitzy would have been endurance (ability to "endure") rather than pure health (body mass and body mass efficiency) as mr. horned helmet who would be stronger than she.
Skill = attribute nonsense - so if Mitzy has never picked up a weapon her "skills" would be baseline. Mr. horned helmet has obviously. Her not using a skill should not have an anatomical effect upon her. Using weapon = stronger = do more damage is not a guarantee. Who would you rather get in a fight with - average NFL linebacker or say someone not quite so bulky (strength) but someone like Muhammad Ali or say - Bruce Lee. I'd take the former option - the latter have obscene SKILL at their profession of COMBAT. whereas the former are really strong and fast.
