Well here's one of the more obvious examples:

More skills don't mean more complexity... It just means more skills. I don't get this... Yes, skill numbers go down from game to game, but is only because skills become redundant, or useless. look at what we know about skyrims skills, athletics and acrobatics are gone... Oh crap you can't run or jump? Nope, those were redundant. mysticism was redundant. they added enchant again, so thats a plus, and they merged speechcraft and barter, oh no! with the addition of the perk system... Its set up for less overall skills, but
more complexity within the way you can build a character. the spell casting system may take a hit due to the probable spell creation axing, but the spells themselves due to multiple effects per spell. so magic is still up in the air, but spell making was broken anyways. if you mistake complexity with clutter, thats your issue, but please, don't ry to fool everyone else into thinking skyrim will be simplified to the point of being
linear if I remember from your first post.
