The Lore of the game doesn't interest me. I've tried to read these books scattered around BUT most of them don't make much sense and i simply find them boring. They just seem to cater for the hardcoe LORE types.
Having to fast-run constantly back to whiterun and visiting different vendors to sell my items is getting rather tedious. Half of them have hardly any gold also.
Looting all the time and getting the same items time and time again also is getting boring.
The interface is terrible for PC users. Constantly pausing game to equip etc. It breaks up gameplay. Lack of character info screen also means you can't see wtf is equipped or not.
Graphics look great in some areas then become like Oblivions in others. It seems like the developers thought give areas around whiterun the best appeal as thats the first place you set foot in.
And to make matters worth i heard you can get the best armour/weopon in the game with 8000 gold and smithing. So whats the point of adventuring? Kills the idea of questing for the golden fleece.
Just my tuppence worth

) But I only cleared maybe 10 medium sized dungeons so far and a few small forts. Did about 20 quests (counting chain quests as one quest btw). There's so much you can get out of Bathesda games. Take your time, explore and immerse yourself. If you're making a melee character, focus on quests, perks, exploration, etc etc that favour melee and so on and so forth with other "class" types. I forsake all magic and ranged on my Nord Barbarian so dragon fights (on expert/master) become longer and more challenging. Hell even caster mini bosses you really have to plan it out. For us die hard ES fans, it won't surprise me at all seeing some of us (myself included) sporting total gameplay times of 500+ hours which is absolutely amazing for a 60$ game
