Ty told me about MS Monopoly, a board game making fun of Microsoft's so-called monopoly. You can't really play the game, but you can click on each of the properties and see how Microsoft has purchased companies and used them to their advantage, usually in very sneaky ways. Also, you have to check out the "I'm So Mad I Could Sue" section, which includes a nifty online form which allows you to sue the website owners. :)
