I don't know how you can say that with a straight face. DAI is clearly heavily influenced by Skyrim's quest/explore model. I don't view it as a negative, but it's there and pretty blatant.
It is influenced.
It is nothing like Skyrim when it comes to the actual world and exploration.
Skyrim's world is alive and reactive.
NPCs walk, talk and work, have day-night cycle, react to you (try walking around naked, for example), guards react, you can thieve and kill if that's what you want to do, etc.
it's a world - in which you happen to be existing and doing your stuff.
DA:I's world is in which the NPCs stand eternally in one place, they don't walk or talk or react to you, there's no day-night movement or cycle.
It doesn't feel like a world - it feels like a playground which was created specifically for you to play in. The world feels "fake" - especially the cities/castles/villages.
This is stuff I don't mind in a party-based, story-driven game like DA:O... But when the "open world" and exploration is a huge part of the game - then yes, it is very jarring to anyone who enjoys a proper open-world game like Skyrim or Oblivion etc.

In Skyrim, every dungeon and every zone - outside of a very few specific ones - are level locked to your current level.
You can go ANYWHERE. And anywhere you go, you'll get rewards for doing stuff. There's no level locked loot.
That's "open world" done properly.
IN DA:I, zones are level-tiered (so much so that I actually overleved two zones so completely on my first playthrough I just ended up rushing through the trivial content 3 levels below me).
You can go anywhere, but the game doesn't want you to. Not only can the content be above or below your level by a huge margin, but the loot is level-locked.
You kill a lvl 14 mini-boss at level 11? Good, now wait for level 15 to use the gear he dropped.
Also, once or twice per zone you'll hit an invisible wall and have to go back to the War Table to unlock the passage to some area.
It's a massive immersion breaker - especially if you have to go and grind out some power first.
Once or twice doesn't sound bad, but it adds up quickly.
...
So no, it is nothing like Skyrim.
It is influenced by it, but it is NOTHING like Skyrim.
And anyone who says it is hasn't really grasped what TES games are about.

It just feels like they took certain elements from other games and mashed them together, without really getting into why it worked (or didn't) in other games.
Skyrim exploration, Souls Estus Flasks, Ubisoft gathering flags/shard stuff, etc.
Same goes for combat, wants to be action based and tactical at the same time, ends up being good at neither.

Anyway, said this on this forum before, 7.5/10 game for me (finished twice).
Good game (mediocre at RPG elements), but just not great.
Closer to KOA:Reckoning tier than Skyrim/DA:O/Dark Souls/etc.
