Online games
Here are some games that can be played with your browser, thus you don't need to download the game to your harddrive.

Some of the games, however, require a plugin. That is a small, one time download, that enables you to play all games designed for the plugin. You should really consider downloading it because a lot of sites use or are planning to use the Vitalize technique for interactive content on websites.
