Enemies are not automatically leveled to your level
The other thing that was immediately clear from the start is that the game has an isometric 3D view.
As far as quests go, there will not be any fetch quests in Original Sin.
Like in the first Divinity anything that is not nailed to the ground can be used. Again, you can carry around anything that is not too heavy like a bed or a barrel (as useless as that might be, but if it makes you happy, you can). And you can also throw a barrel at an opponent, use a broom as a weapon to hit someone with, or break a crate because it is blocking your way.
However, there are two characters - one of them can lure the owner out of a room and the other one can then freely browse through the available stuff and take what is needed.
Combat is turn-based and takes action points.
Original Sin can be modded. The same toolset as is used by the developers will be delivered as part of the game. Also, all the objects, tile sets and characters in the game will be delivered together with the toolset. There is no programming skill required to use the engine as they have made things very simple to use.
