I mean aren't RPGs supposed to be about player skill in any form, wether it's about intelligence or reflexes?
In a ARPG with "a player skill in any form" you can't have a character you want. You can't make it balanced. And you will always have the same character. You won't make it more intelligent but weaker. You won't make it more stronger but less intelligent. No matter in what shell you will put it - it will always be the same character. Because your skill will be always constant for that character. Unless you will presume at times that your character is f.e. weaker than it is - and that will be a retarded LARPing.
And your character will always have the same combat experience. The same twitchy combat. And that bores me to tears.
Now RPG systems let you create a character you WANT not a character you CAN. See the difference?
And player skill will always be there. FO has many choices - and it really takes some intelligence to understand that you should not tell that guy with a big shotgun to kiss your ass. It also takes some intelligence to think about how to get out of the town where you just killed its mayor.
