All,
As with any forum, when in doubt, create your own thread. It is the best thing to do to get assistance with your specific issue. This thread was started to discuss DirectDraw issues specifically. If you have a problem with a game and you are unaware if it uses DirectDraw or not then it is probably safer to start a new thread.
Squall,
Most of the games you have listed are either not Windows 7 compatible or are currently unknown in their compatibility. Make sure to check the Windows 7 compatibility center for any software before trying to install\run it on a Windows 7 machine.
Starcraft (information pending)
Worms (not listed for Windows 7, listed not compatible with Vista)
Sierra's Pharaoh/Cleopatra (not listed for Vista or Windows 7)
So with that in mind the only thing I could suggest would be to right click the game .exe file and change the compatibility mode to XP. Also depending on what version of Windows 7 you have, you may able to install XP Mode and run it with that.

a couple of these games i was wrong in indicating, DirectDraw applications that use 16bpp work fine, these include HOMM3, Pharaoh.
However Starlancer semi freezes, with CAD working to get out of it, whilst games that mix DirectDraw (DirectMedia video's) and D3D, and straight DDraw 256 colour titles freeze the system entirely, these include Starcraft and Age of Empires 1 and 2, of which of which you mark Starcraft and Rise of Rome as compatible with windows 7, where the hardlocks are still happening as well as color palette corruption.
