If I had to pick just one thing it would be more camera options.
The high angle iso style tilt and tight zoom maybe looks more cinematic but isn't giving the full party control vibe I'm after in Baldur's Gate. I'd like to pull way off, god-mode style. The current default max zoom reminds me of like going back and playing BG1 after BG2 came out, just too zoomed in. I always find myself wanting to pull back as far as possible to see more of the environment. Either that or I want to be more in the drivers seat for the run and gun with the full tilt, including up hehe.
