Well I certainly never expected to be hugely disappointed with this demo. So far this is a huge step backward from Divinity 1. I'm not one to care about the voice acting, but man did it get bad. The main problems with the game are the following:
1.) Stamina runs out in about 1 second and you're walking at a snails pace.
2.) Combat is so slow it looks like it's happening in slow motion.
3.) You can't scroll around the map using specified keys (wasd would be nice).
4.) Related to above: Very annoying to have to move mouse cursor to scroll. I found myself hitting wasd (opening automap a lot) trying to scroll around the map.
5.) Selecting and attacking enemies was way easier in Divinity. After setting my characters to aggressive they went off and attacked on their own, but I had some issues getting my main character to attack when on normal mode.
6.) Why can't I bind a key to select all units?
Overall it seems pretty half-assed so far, hopefully it's just a poor demo.
