This may not be quite the right thread, but here's something interesting:
This is an early screenshot of Alexander confronting the Lord of the Dead in KQ6.
In the final game Alexander's sprite was completely redrawn and his costume altered slightly.
In the WIP screenshot, Alex's costume is modeled more closely on this drawing seen in the KQ6 hint book. Interesting that the image seems to show Alex with longer hair.
There are also four early concept sketches for Alexander's costume, which likewise show him with a mane of long, flowing hair.
Much as KQ7 Valanice's appearance reuses some things from an early sketch of her for KQ6, Alex's early long hairstyle was later given to Edgar in KQ7:
I should also mention that, as can be seen in the Making of KQ6 video found on the game CD, the actor who played Alex in the motion-capture sessions seems to have had long hair tied in a ponytail (visible at 2:36 in this video
). Perhaps this was a remnant of the "long-haired Alexander" idea? Or was it just the actor's actual hair, and thus always meant to be edited out later by the artists?
Akril, a few notes on miscellaneous things on your site:
The early "granite" high-res Sierra logo from the KQ7 resource files is actually the one used in the Windows version of Gabriel Knight: Sins of the Fathers
The motion-capture animation of a StarCon red-tuniced officer waving around a stick from SQ5 seems to be intended (in my guess) to be an officer cleaning a window with a wiper, as seen through the glass from the other side. It was probably scrapped because the guy isn't wearing a spacesuit.
