Earliest memories of video games were titles such as Aztec, Spy vs Spy, Frogger, King's Bounty.
But what really got my eight year old mind captivated on a summer vacation in the 80s was Elite on C64. I've spent hours into the night trying to get as far away from Lave as possible, all while trying to make some profit on hauling food and computer parts. I did not understand the concept of saving and loading a saved game back then, so there was a lot of trial and error into permadeath involved.
