I failed to see how you can reach 81 level, complete every non-repeating quest, talked to every NPC, collect every uniquely named item, collect every book, master every shout, acquire every spell, find every POI, get every enchantment effect and get every ingredient effect within a 160 hour playthough on a single character. Nevermind doing it over 3 characters.
Do you TCL and movetoqt all the way?
I did pretty much everything over the course of three characters. I only did the main quest three times and all the guilds on one character one time. I keep my guilds seperate from each character because its silly that i can become the head of everything in skyrim. I never got to level 81 not even close because once you get past level 50 nothing scales any more and there is no increase in difficulty. Level 35-40 is the norm for my characters to retire. I just start over with another character and take a different path. Generally my playstyle is to play "pieces" of the game with different characters, I even go so far as to have my Nord focus on the nothern and rural parts and my imperial is a more cosmopolitan who sticks mostly around cities..........yes i have a compulsive issue with roleplaying characters that make sense. So basically no single character has ever completed the whole game nor will it ever happen for me. My character isn't THAT special.
Have i done every enchantment?......why would I? Why would i bother with a frost enchantment when frost trolls, ancient dragons, icewraiths and draugr are everywhere. I used the ones that made sense like absorb health or fire damage.
Why would i pick up every book........I have read most of them in oblivion and morrowind.and there weren't that many new ones that i encountered.
I talked to every npc i could find in every town i could find. It sounds to me like you are just trying to make a false argument for arguments sake. At most ive missed a few hours of hidden quests somewhere out in the corners of the map. The one thing that this game does do well is it makes you go all over skyrims and i tend to stop and explore any locations along the way. If I powergamed i probably could beat the main quest and the guilds and the daedric and large city quests in less than 40 hours easy. This game is by no means overflowing with quests. The only time i fast travel is by carriage or if i do something really stupid like forget a claw key somewhere. so sue me.
