Overcomplexity, however, is not a virtue for its own sake. Complex, with a good, flexible user interface, is great. Bad user interface is just bad, regardless.
I certainly found the BG interface to be awful, and despite the fact that it's a known good game, I couldn't manage to continue it. Not to mention it uses the haphazard and murky D&D rules. Planescape Torment on the other hand, was a delight.
On DAO2, there is some info that says the gameplay on the PC will be very similar (not always a good thing either) to DAO. Most of the gameplay videos are from the console versions, which are said to be much more actiony. This could be a example of the PR people shooting their initial PC sales in the foot.
