OP doesn't understand what a linear game world is either.
OP...do you even understand "linear"?
It seems several people don't understand what linear means. Sad really, because they continuously hold onto the idea that they're right in spite of proof to the contrary.
Scripted events can be avoided in Skyrim. Just activate them and go on your way. You are not obligated to stick around and watch the scripted event unfold. If you were rooted to the spot for the duration of the event, then I'd be inclined to agree with you, but you're not.
Oh? You mean the miscellaneous quest for that collector? The one that has you seeking out these statues for someone else... Stones of Barenziah and Dragon Priest Masks (included because they're collected for a reason other than personal want). No Stone Unturned may have to be activated in one way, but you don't need to activate the quest to collect the stones. You can collect the lot before speak to either Maul or Vex.
And avoiding them doesn't make the playthrough different. You're lying to yourself there. I'm talking one character discovers something another character does not, such as a murderer discovering the DB, a thief discovering the Thieves' guild and a dungeon diver discovering the Alyeid statue quest. Here? Every single quest is obvious as day, sitting there waiting to be activated via a scripted convo. There's no difference in my mage, thief and warrior when it comes to these quests; all three of them will discover the quests equally.
So you want a gameworld where nothing happens unless the player wants it to? I'm sorry, that's not how TES works.
So you go through life noticing everything that's going on around you, listening to everything everyone says? Wow, I'm surprised you have enough time to play Skyrim to complain about it.
Actually, it wasn't important. "you can choose what level you want." And? What's your point? It has nothing to do with the topic at hand.
