When playing Oblivion I noticed a lack of explanations for stats.For example,the character creation part of the game didn't tell you in numbers what the starting skills/attributes of each race was.
Another example is it doesn't tell you that your damage won't go up further from strength once you've hit 100.Effectively making strength enchantments/spells near worthless.
I think think they need to add notes explaining these kinds of things.There's no reason that I should have to buy a book or go onto the internet to learn these kinds of things.
