Very happy with the Spiderweb games (including the graphics) - prefer them over BG and DA games: easy on the mind, my old eyes and fingers.
Avernum is far to small for me on my native resolution you can tell it was designed to be played on much smaller resolutions, even scaled down to 1440 x 900 it's still rather small!
I don't recall seeing this issue in Avadon though.
