I played Buzz Aldrin’s Race into Space. Or At least, tried to. It was horrendously, horribly broken in its design and execution. It was essentially impossible to win. For example, your first flight of a man into orbit might have a 10% chance of success if you didn’t launch an unammed mission first. Chance of success if you did? 11%. If you did have a failure the reliability of your vehicles plummeted dramatically rendering recovery from such failures basically impossible. The concept was good but as a game it was just odious.
