From what I have read here are some explanation of why some features (only the one I really care about) are not present in the game:
1) Attributes
My understanding of Bethesda choice: You don't really need them as they are used only to calculate Health/Stamina/Magicka
My reaction: Ehh, I must be dreaming???? Really??? What about some sensible way to roleplay? What about having more dialogue option for intelligent character or wise ones? What about having a quest only if the character luck is over 80? What about a dice minigame based also on luck? What about swords/greatswords that you cannot use as your strengh is not enough?....It seems to me that 30 years of good RP mechanics are a bit too easily dismissed as irrelevant. Sure perks can do some of these things but it seems really odd.
2) Mark/ recall
My understanding of Bethesda choice: They break the game
My reaction: Well...they are supposed to!! Apart from that it doesn't seem so difficult to change these spells so that they can be activated only if certain conditions are met. For instance, in a dungeon I would make them castable only if there is a light coming from outside (like in the game trailer) and no enemy in sight. May I miss some part of the game by using them? Maybe but that's is the beatiful part of it...do I use them and risk loosing something cool or I don't and explore everything?
3) Levitation
My understanding of Bethesda choice: it breaks the game
My reaction: Again...come on...what kind of answer is this? You can implement levitation the way risen has done it and it wouldn't break any game mechanic, or you could do it the Oblivion way and have some forcefield/whatever guard the major cities and prevent you to fly in (which would make sense due to the presence of dragons). Inside dungeon you just have to make the ceiling low where you don't want the player to take off of invent some other ways to do the same trick (Poison gas/spikes/moving part...) For intelligent people like bethesda folks it doesn't seem a major challange.
4) Spellmaking
My understanding of Bethesda choice: it breaks the game and it's not needed because you can use your hands to change the power of the spell.
My reaction: mehh...??? Spellmaking was never about only power (aside from the occasional super fire spell we all are found of), was always about smart ways to combine spells and train you. To me it was the essence of roleplaying a mage.Can it really be so difficult to limit the OP spells available in spellmaking?
If Morrowind was created by 20 people, Oblivion by 40 and in Skyrim the team has balloned over 100...I wonder what are these guys doing? They seems to have so many things less to do (Spears/Crossbow/Greaves/...) are they all sweating on the PS3 conversion or do this figure include translators in 6 languages?
Come on Bethesda...challange yourself!
