The class system, mostly. That and that it tends to deal with Ancient Greece and other Ancient empires and their system of gods and fantastical elements. In Titan Quest 1 we went to China, Egypt, etc. etc.
But you won't really deal with any of that in a Early Access.
On a side note, I think their movement system needs a tiny bit of work. If you play with WASD, you could make the mouse and movement work in the same way it works in POE2. The way your character moves and reacts with which direction you're looking makes the animations considerably more fluid. Right now my character is extremely janky with WASD movement.
