'SimCity 3000' is one of the most famous games in the 'construction and business-management' genre, for short, the city-builder. And that's what it is, the player builds the best city they can possibly make, trying to earn as much money and have it be a home to as many people as possible.
The game takes the gameplay of it's groundbreaking predecessors and fine-tuned it further to give a more realistic gameplay experience. There are many more things to build and zones will grow in a way more realistic than ever before and now, neighboring cities come into the mix although their influence remains minor.
I had played 'SimCity 2000' fairly regularly already, and the new game quickly grabbed my interest. It wasn't however, until I saw one of my aunt's cities that boasted many skyscrapers and luxury apartment buildings that my interest really peaked. I started creating city after city and each one got better until my magnum opus city got to around 350k inhabitants, using only half the map. The interest then moved on to another game years later, but definitely remained in the genre.
