YoYo Games makes it possible for people without programming experience to make real games. Download software called Game Maker from YoYo, and you can create, upload, and share your own PC or video games with thousands of other users. (You can't play the games online -- you have to download them to your computer.) YoYo Games also has resources for game developers, such as forums and downloadable software, to help users make their own games. The company already has 25,000 registered users and nearly 3,000 users.
