www.Games.com
As you might suspect with a name like "Games.com," this website is one of the largest collections of games on the web. You can play most of the games without downloading them, although there's a lot more options available to you if you don't mind a little downloading. Check out the free casino, and then if you have the skill and the guts, play for cash.
This site has everything from board, word and arcade games ranked and listed so they are easy to find and get started. Even though it is owned by AOL, it has a really simple and effecient design and doesn't seem overhyped or charge you to play.
Go kill some time, play around and let us know what you think...
