DrIstvaan: Pharaoh, like the other classic city-builders, was developed by Impressions, and developed by Sierra.
Protoss: I have it without the expansion. Definitely worth to be bought again. ;-)
As for the others... rather not, except it is Zeus or that China builder ("Der erste Kaiser" in Germany) or something else after Caesar 3. But I still think Pharaoh is the best because of the monuments.
Yes, Caesar 3 had its more than fair share of quirks, which, especially compared to the streamlined nature of those later games.
Still, I wouldn't mind if it showed up here,
IF we get the other ones as well either before it or soon afterwards.
