Marble Madness aged incredible well, as if its makers knew there would one day be a retro-mania spanning across media such as music,film, gaming etc. So all the innovations used on the cabinet - the trackball used instead of a joystick to help you immerse into the game's world and its unique physics (and no buttons- a sincere thank-you to whoever came up with this idea!), the stylish graphics that could pass for some contemporary nostalgia-driven graphics of today, the interesting soundtrack that used a unique Yamaha audio chip that propelled this 1984 title to an almost 16-bit era soundwise. And it's as hard as an 80s' game gets- I remember being entertained and frustrated at the same time playing this in the arcade.
I have yet to try it on some emulator and although I guess it won't feel the same, it'll still be worth revisiting for its architecture and physics.
