Skyrim is as good as todays RPGs get. Compared to the ones 10 years ago skyrim is nothing but an action adventure, but today it is an rpg. Its a bit sad the industry has become like this..
RPG games are not designed for the "weirdo's" that hides out in dark basemants playing Ad&D, looking at the P&P rpg games you see the same trend there also. Compare AD&D to D&D 4.0 and you will see D&D is nothing but a simplified version that is meant to attract the masses rather then the minority of players. Same trend in gaming industry, it's not meant to satisfy the minority, but the mayority of players. That's why it's not possible to kill an entire town in Skyrim, by killing essential quest NPC's mayority of the playerbase would gimp themselves and thus destroy their fun because they aren't ready to face the reality of what they just did. And it is with the mayority of players the income is, if Skyrim sells 5 millions compies worldwide rather then 200.000 copies to the "hardcoe" rpg players it means a huge difference in income. So the only realistic businiess though would be to make something both can enjoy rather then try to please just one part of the group.
There are elements in skyrim that could have beens tronger RPG wise, but Skyrim is till an RPG based on the definition of what an RPG game is. You assume the role of a character in a universe. Your actions will to some extent decide the world around you, you can choose to kill the Dark brotherhood or rebuild it. It's not a mayor impact on the world around you other then the fact certain of the people you kill are rather important storywise". I can agree that these elements could have been done a lot better, but for mayority of players they would have hated having to micromanage a guild. I would have loved to be able to assume a more direct role of the thief guild, for instance Iwould be forced to spend some time every week on accepting missions and which of the members should do what job, and by choosing the correct member for the job I could also improve their skills or at worse risk the member being caught and jailed or possibly killed. Same with the other guilds also, I would loved to be able to control and decide which path they should take for the future.
Dialogues is a bit weak in Skyrim as your response to a lot of them seems to be not really having an affect, I would loved a karma system that based on your actions gave the NPC's a different reaction towards you. For instance I who play an Thief/Assassin would be noticed as a shady character that people would have a harder time to trust with information, to counter this a high speech skill and perks could make you a bit more easy to accept by people. On the other hand a player who play's a Paladin type of player would then be seen as a person who helps other without thinking of himself and from certain people he would be easier to trust and then get easier access to some information then a thief would do. I would also liked the option on quests to have options on ending them. When you are being sent out to look for Amren's sword an option would be to keep it for yourself, and not give it back, thus failing the quest and giving you bad karma, or increasing karma by giving the weapon back. Clothing should have an effect if you enter a city in full armor and weapons people should react differently towards you then if you entered the city in normal clothing and maybe a dagger as your weapon. It would be nice har resting andeating actually did something other then giving you faster skill gains and regen, that you actually had to rest every night and eat every day to avoid being fatigued. All of these things would have improved Skyrim as an RPG for my part, but for the mayority of players they would more likeliy have felt these changes to be bad and unnecessary time sink that prevented them from enjoying the game to the fullest.
Still I categorize Skyrim as an full blood RPG as it does allow me to interact with the world as an person rather then just view the world as a story being told. is it the perfect RPG, no not at all, but so far the perfect RPG has not been made either.
