checkpoint

After finishing Seastalker, he had the idea to write a Cold War espionage thriller, tentatively called Checkpoint: “You, an innocent train traveler in a foreign country, get mixed up with spies and have to be as clever as they to survive.” He struggled for six months with Checkpoint, almost as long as it took some Imps to create a complete game, before voluntarily shelving it: “The problem there was that the storyline wasn’t sufficiently well developed to make it really interesting. I guess I had a vision of a certain kind of atmosphere in the writing that was rather hard to bring off.”
