This was one of the first strategy games I ever played, I think I was around 6-7 years old. Immediately fell in love with the setting, gameplay mechanics and overall musical feeling it provided.
Of course, since English isn't my native language and I didn't know it that well by that age... Back then I never figured out how to transport resources between islands, leading to situation I never was able to finish last Egypt campaign mission. Every once in a while I started game from beginning, beating game first as Romans, then Asian and lastly get myself stuck with Egyptians.
Until couple of years ago I finally managed to finish that deed of mine.
Even still to this day, i feel like Settlers 3 is one of the best strategy games ever made, having engraved it's sweet little spot forever into my heart.
