Yeah I only wanted to become janitor of winterhold but those darn respawning items and npcs reporting me for picking up thier items spoils that.
This is more or less the same as the complaints about a decade ago regarding boss fights in platformers, it's a nessarcery "evil" without conflict, danger and you being a part of that there is simply no game. You don't want to be head of the thieves guild then don't, the controller is in your hands not the games but if you want to take that a step further and say remove Alduin, the Eye of Magnus, Thalmor and Nocturnal from the game you're only removing what choice and impact you can actually have within the game, which already isn't great. Would you really like to play TES:VI Morrowind, you can wander a wrecked place doing nothing, there is no danger, nothing to save and no plot.
Sure there are ways round it, Fallout you don't really "Save the world", in new vegas you barely have an impact period, much to my dissappointment finding my choice was railroaded into the same wall as the other. But there is a threat and something to deal with. Bastion took it another way, you're lied to thoughout the game saying your doing what is needed to "save the world" but you cannot, still the threat and objective exists and it needs to.
I'd suggest if you are that sick of being needed in a world that you avoid mainstream RPG's for at least another decade, even then it'll be a common theme. I don't see how tripping over the "save the world" switch as your mopping up sick would make for a better option, or how being no different from belethor at the store would either. Might be cliche but whether your unique, have a higher calling or just fall into these things all amount the the same thing. Although being given an honourary position of the guilds would make more sense, you helped them out so much but you need to be elsewhere being the most useful person around surely they don't want you to stand round doing paperwork and flinging spells at a wooden board.
if your referring to the gameworld,in FNV i had FAR more impact on the game world than any other game ive played with the exceptioin of RTS games or minecraft. while you werent stopping the world from being destroyed by dragons (real original idea there bethesda) you were stopping the advancement of the legion from taking over one of the last remaining cities of the old world......or helping the legion, or helping house or even helping yourself. thats a hell of a lot more impact than skyrim or any TES game offered. if you referring to the world as in the immediate area of vegas versus the entire earth well then yes.
for skyrim specifically the navy seals that hunted down and kill terrorists like bin laden and others do extremely important work (quests) for the navy (guild) and yet they arent automatically made admirals or the president or even senators or some other political leaders. they might promoted up in rank and given some extra leave time and a bonus or something. even though they might have very well had more of an impact on the world stage than an admiral. they are not automatcially made leaders just because they did what they did. people that assume that you are made the head of some organization automatically just because you do something important or even awesome clearly havent been out in the real world that much. thats not even close to how it really works. the fallout games were much better in this regard and gave you the appropriate reward and rank but did not hand over control of their entire organization to a complete stranger. that is just silly.
people also forget that without Tulfdor you would not have been able to complete the quest at all so he was just as important if not more so than your character. i forgot who helped in the fight with a certain asshat of a high elf later on (might have beenTulfdor or archmage cant remember) but they also were just as indespensible and you would not have succeeded without them.
for the college you should get a nicer room, access to the archmage quarters so you can gather the ingredients (although if you go at night he should be cranky and kick you out)

and maybe some nice gear, but thats it.
maybe after you do all if not most of the sidequests and a bunch of miniquests AND you were actually a mage character that mastered in at least one school and was expert in several others THEN i could see being an archmage. but not till after you have done buttloads of work for them and spent alot of time with them and actually had magic skills.
the suggestion that you avoid having to save the world by not doing quests is just dumb. i dont have an issue avoiding the main quest but if i dont want lead a guild i have to avoid doing around 20+ quests and not being able to get those rewards or dealings with certain NPCs.
