Sacrifice was the first game I purchased here at GOG. It did have the pagefile error, however, after I notified customer service of this inconvenience they modified the code and uploaded a new installer for the game. I have run this new version without any issues successfully with a pagefile of 3072MB.
Customer service was fantastic on this issue and I applaud their responsiveness.
Great - I'll probably get this at the end of the month then when I should have some free time.
