I can't play more than 30 minutes of Skyrim in a game. After 30 minutes I am so bored and just feel like playing the game is a chore and not fun at all that I just turn it off and never again load that game.
I try to play it every year thinking that maybe I was being too harsh and also because I really want to like the game (TES was one of my favorite computer game series since I played Daggerfall back in the old days).
The game writing does nothing good for me, quests are "meh" for the most part (I liked the one to assassin the emperor when is ship is leaving for example), the puzzles can't even be called that, things happen "just because", the civil war that is ravaging Skyrim is non existent, the streamlined character progression is boring as hell, the Shout system is ridiculous, the consume dragon souls is ridiculous, the factions are paper thin and ridiculous, you can rise in any faction right to the top by doing menial quests or just by doing a dungeon, dungeons are linear, settlements are boring, enemies are boring, enemies dodging arrows and crossbow bolts shot by our character while we are hidden and not detected and the enemy is facing the other way and then like magic they just teleport a couple steps to the side to avoid the projectile, the stupid and ridiculous pickpocket system (oh, now I am so good at it I can steal the clothes people ARE WEARING without anyone noticing it...), the "can join every faction with little to no effort/skills possible", the become teh archmage even if you can just cast a low level healing spell, the world does not react to anything that happens, guards magically know what you're good at and what factions you're on just by looking at you, the changeable birth sign just by looking at a stone (in older TES the birth sign was just that... a birth sign. Your character was born in a specific time of the year when the moons and stars aligned in a particular way that gave him/her a special power), no one seems to care what race we play with (IIRC there might be one or two small dialogues in the entire game where someone might comment on our race), levelled loot and rewards (I even remember seeying years ago a mod to make some quest reward items to level with the player, because the way the game is set is that if you get a reward from a daedric lord, and you're low level, you get a crap weapon or armor, but if you do that quest at higher levels you get the same item but much more powerful... Daedric items being as shitty as low level steel equipment...
), etc... I could go on and on even more about what bores me in that game.
Good things for me are:
Character appearance customisation, music, graphics are improved over older games, can't think of much more but I am sure I am just forgetting some things
.
I can see why other people enjoy the game, but my brain doesn't like it and makes me feel bored fast when I play it. Modded, unmodded, total overhaul, it doesn't matter...
This is just my opinion. I only posted this because you asked for people's opinion and I decided to reply honestly.
