Interesting times we live in where people choose entertainment as a means to suspend the use of their brain rather than excite it.
You can choose to invent your own mental sock-puppet roleplaying in Skyrim or any other game you want, and I'm glad you enjoy doing that, if it rocks your boat. But the fact you can choose to invent your own personal roleplaying mind-games within Skyrim, does not relieve the game developers of the responsibility- the paid responsibility, to provide a good variety of interesting and *replay-friendly* built-in roleplaying opportunities, devices, and components. Instead, you got the linear, low-grade, forgettable and entirely replay-unfriendly quests that were tacked onto the world in Skyrim. You got dungeons and limited loot and enemies that are exactly the same in every way no matter how many times you replay the game. You have a gameworld that shows not a nick, not a dent, barely even a micron of change or difference or variety or indication that you even existed there or affected it one iota, no matter what you do or how you decide you want to try to play the game.
You are therefore ultimately forced into adopting the mental sock-puppet roleplaying mode, once you come to the inevitable realization that the game itself certainly isn't going to provide you with any of those interesting varietal experiences, once you've burned through the limited and quite mediocre 'RPG' content that's included in it.
Me and my buddies had wild fun inventing cowboy vs. indians scenarios in the backyards and playgrounds when we were in gradeschool... when all we had work with were some long sticks and our imaginations. That's pretty much where the devs leave us in Skyrim, once you've ogled all the scenery and the done 'n gone main quests are used up. Sure, I could imagine I'm some insane thief who only wears a loincloth and only steals mammoth cheese from giants on odd tuesdays... but frankly, I'd rather have the game made well enough so that I'm not forced to go that route just to have something semi-interesting left to do in it. I thought I paid for more than just a long, pretty stick.
