My mother sold both my Atari 2600 AND my Commodore 64 with games for about $50.
I had at least 40 games for the 2600 and around 1000 for the C64 (many of which I would still be playing today - Movie Monster and SIlent Service were two of my favourites)
I've still got an Atari 2600 Jr. and 30-ish games. I also recently picked up a TI-99/4a computer, and have around 20 games for that. That thing's a classic.
