Retro games hold a timeless appeal. The were so simple to play and they hold that nostalgic value where you get excited when you see a game.
They often had engaging storylines, art styles that you'd never forget and memorable soundtracks. Remember the Donkey Kong soundtrack, or Super Mario?
Newer generations will never know that a 'repair' was just blowing into the cartridge and it would work again!
We will never forget how these games changes the world! (We have some here at Electronic Fix if you're interested)
