The enhanced edition now supports any resolution one may have on their PC as well as has a new addition of being able to zoom in and out, making it much easier to see what is going on in the game.
The game's open nature and lack of strict gating can make it seem imbalanced, as you can be overlevelled in one area and very underlevelled in an area next to it.
Plays just like the original game with the same hidden treasures. When creating PCs, you have more available portraits to choose from. Black Pits Arena combat module is awesome, but gets really deadly in the later rounds.
