Here's the PC Games in the list.

1. The Sims (PC - 16 Million Copies Sold)
2. The Sims2 (PC - 13 Million Copies Sold)
3. StarCraft (PC - 9.5 Million Copies Sold)
4. World of Warcraft (PC - 9 Million Copies Sold

Three of which I own :-).

It's interesting though to see some of the other games that made it to the top, such as Nintendogs, a pet simulation video game developed and published by Nintendo for the Nintendo DS handheld video game console. It was first released in Japan on April 21, 2005, and was later released in North America and Singapore on August 22, 2005. Although it looks cute as hell, I wouldn't buy it. But then again, I'm not a kid. Guess I'll have to to track down my cousins and see why they play it. But here is the question, are there really 14.75 million kids out there playing this game?
