These kinds of things are typically just a money sink. When was the last time you played an Atari game? How often do you find yourself wanting to play them?

I bought an Atari Flashbacks for my mother, and she played it one time. The ColecoVision I got her, she played one time, and that was a console she grew up with. Nostalgia alone isn't enough to really justify buying it, especially if you only use it once and then it collects dust.
