I want to enjoy the game, I can see it's redeeming qualities, but I just can't, maybe I'm not playing in a way that's enjoyable, so I'd like to know how people have fun with this game.
Two things helped me enjoy it more:
1) role-play idea
2) Mods - really, without it, it is easy to find O a little dull or at least lose a lot of interest
(Also, maybe it is indeed a game you cannot enjoy, but let's give it a try, right?).
The first is actually the hardest, as it depends on what you want, given what the game offers (the mods will only make sense AFTER this idea).
My favourite character was a Shadow Assassin with a background story that showed why she had a grudge aginst the empire. She spent her time figuring out ways to bring down rulers, nobles and imperial guards *undetected*, but her higher target kills always had asignature: she left a bouquet of flowers (or whatever flowers were found).
She used only a bow and carried 20-24 arrows *only*; no armour, only that black robe and hood for the operations, elegant / noble dress for 'social interaction' and thongs for her seductive / lascivious conducts (hey, I'm a man, I like to see these things sometimes

). She'd have low Str / End, high Int, Pers, Agility and Speed. Her skills were: Marksman, Sneak, Acorbatics, Alchemy, SPeechcraft, Security and Illusion.
She'd never fight in arena for fame, coz fame is not in he interest; she'd join every guild possible (using different disguises), coz getting hgiher in those ranks could provide easier access to high-end targets. When part-taking in a main quest sort of thing, it was solely for the purposes of deception, giving out the wrong idea that she was an ally, only to be able to murder the key gurads / nobles / rulers characters.
MODS
Now - I managed to use some mods to make this all mor fitting to her (No Psychi Guards, Beauty mods, Repair Arrows, Thief Arrows, etc...) . Only my machine cannot handle O, so I got tired of installing, reinstalling LOTS of stuff, over and over... But I was enjoying it a lot.
Now, whats YOUR style? Your character concept? How do you see him approaching things / situations / social stuff? Only when you somehow start answering these questions will you be able to shape your character more lively.
Do not give up - research, ask, etc... It takes time - Acadian herslef has a hell of an awesome build, just check it out.
