Frontier: Elite 2

The game's copy protection was worked into Frontier in the form of police spot-checks, making sure the player is the legitimate owner of his ship. At certain intervals in the game, the police would ask the player to: "please enter the first letter of word X, row Y on page Z". If the player entered a wrong letter on three occasions, he would be arrested and his ship impounded.

Frontier was generally well received by the media. Most magazines were awestruck by its sheer scale and accurate depiction of real-world physics.
