For nearly three years, Xbox 360 owners have been downloading and enjoying games on Xbox Live Arcade. Unlike retail products, which often disappear from the shelves and from memory, XBLA games tend to have a longer life cycle. In fact, many of the earliest XBLA games remain among the most often downloaded to this day.
IGN has assembled their list of the ten most essential XBLA titles. They are not saying these are the ten best titles or the only great games. This is merely a list of XBLA titles IGN feel no Xbox 360 owner should be without. These games exemplify what makes XBLA great. If you don't have one of the games on the list and are looking for something to play, then give it a try. You may find a new addition.
