Mine was the old "Phantasie." (I had fallen in love with "Adventure" on our old Atari gamebox, and "Phantasie sounded like the nearest equivalent. It was.)

The very first game I ever played was on a business computer in Papa Elf's workplace. The boss allowed us to "play" on it. (It was after business hours.) The game was called "Star Trek," but it was a far cry (Rev. Spooner strikes again! I almost typed, "car fry") from the simple BASIC games available later. No sound, no video. The point was to shoot down Klingon starships. There was a grid sheet (tediously typed out by whoever had the instructions for it,) which showed a sheet of asterisks (stars) set about an inch apart on one sheet of computer paper. (IIRC, about 9" X 12".) Each star had its position labelled underneath it: A1 thru J10. The player then entered in the co-ordinates (D6, C4, H5, etc., for example.) There was then a command to "Fire!" (which escapes me now.) The Klingon ships ==> then "landed" on "random" co-ordinates*. If the ship landed on a chosen co-ordinate, it disappeared. The player's score was then shown at the bottom of the sheet. Tedious, but I was hooked. * There was at that time no computer which gave a true random result. I don't believe any personal computer yet has that capability.
