Honestly,i am not sure.
Outdoor environments are so well executed that you might not even notice the fact that the game has a single path with few branches available,it's like open world,but it's not,get it?
It doesn't feel cheap,the animations are fluid and crisp,when you hit or shoot something,it feels like the whole hell is going to break loose,props to sound designers,because that is what gives these kind of games a ''punch'',weather effects,rain and snow create nice atmosphere fitting to the environment.
It doesn't feel as if runic just copied Torchlight I and remade some textures to make it look slightly different,which i must say most games do these days (Assassin's creed for example)
The ability to rebind keys is a nice touch which torchlight I lacked big time,along with nice and easy-to-use interface.
Cannot say anything else as it's only a beta.
Characters lack that unique feel,only way you can extinguish your self is by finding class-unique gear,all other armors and weapons look exactly the same on every single character.
Lack of animations,all classes have same exact animations,the only thing that makes them different,is skills at their disposal.
Fog,both outdoors and in dungeons,it makes the textures look pale.
Overall it's gorgeous game as far as environments go,but when it comes to characters,at least in beta they all look and feel too alike,they might of as well just made 1 class with 6 skill trees in it,would of ended up being the same.
