-ultimately, most of the games for the Game.com ended up being failures in the eyes of reviewers, thus giving the Game.com a pretty bad reputation. this was one of the reasons that the Game.com only ended up selling at least 300,000 units. for these reasons and more, the Game.com ended up being discontinued in 2000. 
+sadly, the Game.com ended up being a failure as well, mostly due to poor quality games. the Game.com only lasted 3 years before being discontinued.
 
 however, for its time, it was a pretty competitively priced system. the Game Boy Color was to be released in a year for $79.95, while the Game.com was released for $69.99; its later model, the Pocket Pro, was released in mid-1999 for $29.99 due to the Game.com's apparent significant decrease in value.
