A few obscure bug fixes, the ability to have the game's music on your hard drive as mp3 files instead of needing the CD, a different intro screen, and having the Strategy First logo come up when you start the game. It's all mostly cosmetic changes as far as actually playing the game goes. The two big difference are that Deluxe is (or at least, will be soon) available on retail shelves, and that owners of SE4 Standard can patch up to Deluxe instead of being forced to stay with the last pre-Gold patch.
