If you haven't played ED then you can't truly understand.
Your trying to say the camera in ED is so unique no other game had anything like it! Now that IS a nice camera! However I did play the demo a year ago, and I currently have the PC demo on my computer(because I needed to refresh my memory). Your being picky, that camera wasn't unique or special.
Lastly, on the HUD, if it doesn't give a continuous update of info (ie.. your status bar) then , in my opinion it should be turned off.
No reason to focus on it, relax. The PC version of ED keeps the bar up all the time too.
The more options that are given to a player, to customize to his or her playstyle, the more sales... the more money...
You make more money from advertising more... in WWE all you can do is wrestle, but people seem to like it. Though I do think DKS would sell better if you could unlock cars. The majority of modern gamers have more skills running over enemies in cars than they do using magic or swords, so its something for Larian to consider.
