Commander Keen — basically my childhood in a game. Except my IQ wasn’t over 300, but I was called an “egghead”, heh. Oh and the traveling to space thing. But I did in my dreams. And the alien for a pet. I had a dog. But otherwise, pretty much the same.
The Escapist recounts Keen’s history briefly… published… cough… eighteen years ago.
