Actually, I use XP, and mine are at:
C:\Documents and Settings\username\
Local Settings\Application Data\Ironclad Games\Sins of a Solar Empire
I think the above person forgot the "local settings" part of the link. By the way, why can't that path be simplified.. Sheesh, they are saved to a folder that is buried so deep... I hate the whole Windows "Documents and Settings" way of saving things.
