The Sims

While this is under the "Old Games" category, it isn't really that old, having been released in 2000. The Sims is a very addictive game, because there is no end to it. Unlike most games which comes with endings, you can continue to play The Sims for as long as you want. And it is addictive because you kind of bond with the characters you create, as you develop them along the way, you make decisions for them... it is as if they are the virtual representation of you in a virtual world, allowing you to live out life in a different manner from your real life.

And you can create your own custom content... just visit a resource site for The Sims to see the amount of custom content others have made available for download.

So it is little wonder than this game has been expanded on with 7 expansion packs... and 2 sequels (The Sims 2 comes with 8 expansion packs, while The Sims 3 is recently released). For the most complete collection of The Sims, you should get The Sims: Complete Collection.
