It's important to keep your city folk happy, or they might revolt - and no, you can't slip anything into the water supply. In Sid Meier's Civilization III: Complete, you plant the seeds of a new civilization and guide it turn by turn toward world domination through brute force, economics, technology, cultural influence, or by fulfilling scenario objectives. Civilization III: Complete has tons of enhancements and features, but it's too bad that it took a while for it to be released - PC gamers have been playing Civilization IV for months.

Powerful Visual-Effects Software

Zoo Tycoon 2

Don't feed the animals - but blowing bubbles at them is OK. The latest version of Zoo Tycoon has new play modes, enhanced environment-editing tools, more park objects, and more animals to choose from - all great additions that boost replay value and challenge you to build bigger and better zoos. 

The Sims 2 University

We're geeks, so writing our semester term paper takes priority over partying. The Sims 2 University expansion lets you take your Sim through four Sims-years of college, attending classes, doing assignments, and taking exams, all while making new friends, adjusting to dorm life, and (if you wish) rushing a Greek house - but by the time graduation day rolls around, this school has become a bit of a grind. 

Painter Essentials 3

Picturesque Painting Software

RollerCoaster Tycoon 3

You can experience any of the rides from the perspective of the CoasterCam. Despite the fact that RollerCoaster Tycoon 3 is the third game of the series, it's the first to appear on the Mac. From building rides to controlling finances, you get to play Michael Eisner (oops, we mean Robert Iger) and manage every aspect of an amusement park. Your goal? Build thriving parks that make lots of money so you can move up the entrepreneurial ladder. 

Reaktor 5

Merge John Horton Conway's Game of Life sim with Reaktor's Newscool Groovebox, and you get a groovy beat box. Reaktor is a guiding light for the do-it-yourself sonic set. The latest version extends the app in crucial ways, with awesome new sounds, a load of fresh building modules, and mounds of examples - expect this monster to keep you busy for the next 10,000 years or so.
