There was a very enjoyable game that I played where I drilled for oil and earned money. Problem is, I can not remember the name. The graphics was made up from the symbols available from the keyboard, one of those where you copied the code in Basic from one of those thick British computer magazines in 1970s.
There was Breakout of course, good mindless fun. Big solid shape on top on dark background where you broke of a piece with the paddle below, left to right to left to right, clicking fast on the keyboard to get to the falling white block. Ran in 8K RAM on one of those computers where the screen and keyboard was housed in one solid unit.That was the very first one I typed in, copied in Basic from a Britsh computer magazine, onto the tape in the tape recorder. Annoyingly, it did not work the first time so I had to type it in all over again. Even more annoyingly, me sister beat my record. My father really liked Lunar Lander, but I never got the hang of that one, too difficult for my teenage self.
Another fun one was a horse racing game, seven «horses». It was smartest to pick number one in the inner lane. My younger sister and I picked a horse each and saw who won. One round around the track. The computer raced the horses, that is the rudimentary horselike shapes made up of symbols from the keyboard. Not sure if it had a name beyond horse racing game. Fun times. Reminds me that you do not need fancy graphics and high resolutions to enjoy a game.
