The video game industry raked in more that $10 billion last year in revenues. With games going for $40+ per title it may be worth downloading free demos or reading reviews before buying anything. 99% of all new video games have their own website dedicated to keeping users updated on the latest news, updates, and possible sequels. On top of this the majority also offer free downloadable demos so you can try out a few scenarios of the game or a specific "mission". It's a great way to try out the latest titles before for you fork over your money.

Most web portals such as Yahoo, MSN, BBC, Excite, etc..., offer a wide variety of free games, both puzzle games and action games alike. Just go to the home page and search for "games" or "free games". Other sites such as MSN's Gaming Zone offers a good number of free multiplayer-capable games, while providing free multiplayer environment for store bought games such as Age of Empires, Galactic Battlegrounds, and much more.

If you're searching for that old computer game that you once had but now have lost, try doing a search on google or another search engine and you'll most likely be able to find it or some variation. I recently found the game Populous and Bard Tales, online. Both are a little dated but still good to revive some old fun.
