For future reference, I’m going to leave here two links for you to explore:

http://readonlymemory.vg/the-making-of-lemmings/

http://www.vice.com/read/in-conversation-with-games-industry-legend-ian-livingstone-551

The first one tells the story of Lemmings – one of the best games ever. The second is about Ian Livingstone, the creator of my youth reading material: Fighting Fantasy books.
