Maybe it's worth it for people who still has 2600 carts, but compared to other classic console remakes that all came with more than 10 games, $125 doesn't seem like a great deal.

$60 = https://en.wikipedia.org/wiki/NES_Classic_Edition

$80 = https://en.wikipedia.org/wiki/Super_NES_Classic_Edition

$80 = https://en.wikipedia.org/wiki/Sega_Genesis_Mini

$100 = https://en.wikipedia.org/wiki/PlayStation_Classic

and the games aren't worth $30 each either
