Compared to Civ II, the wonders in Civ III were way weaker. I remember at least half a dozen wonders in Civ II that I really, really, really (REALLY!) wanted to have, but in Civ III, especially at deity difficulty level, I hardly ever managed to get any wonder, also, because I didn't feel it was necessary. In Civ II almost every wonder gave you an "unfair" advantage, but in Civ III you could almost always beat this advantage by building some more improvements. The Great Library is excluded here. But I hardly EVER managed to bulid it. It's a shame...
