You seriously miss the point, as Clement pointed out for you. Elder scrolls is not about the stupid storyline that Bioware focuses on so much. It's about diving into a new world and explore it and gameplay above all, not storyline.
"It would be better if they would concentrate more in engaging story than..." - Are you kidding me?! Hell NO!!! While I liked DA:O (playing it right now even), I'm sick and tired of "RPG's" with over concentration on the story and "deep" characters, placing it above gameplay. Deep characters? Yeah, so fun to just sit through their chit chat, just choosing the lines that will give you most approval. Because why not? Why would you not? Every interaction involves saving the game, listening, trying out lines, reloading, picking the best ones, repeat... Ugh... You simply clean up every quest, kill everything that is killable, take the most profitable actions. It provides choice? What choice? I'm forced to accept and do every quest, fight everything that can be fought with. Why? Because I lose on the XP otherwise and there is nowhere else to be found, now is there? I can't just go to the countryside and kill some darkspawn, now can I? I'm forced to take the choices that gives me most money. Again for the same reason. There is only so much money to earn and I must earn it all if I want to get those expensive, most powerful items.
