I had never played Broken Sword, but when GOG gave away the first Broken Sword after the 6 milions (or was bilions?) of downloaded games promo and I played it and finished it, I thought: "Man, that is one hell of a game! when GOG put the other Broken Sword games on promo, I'll definetely will take it!" And here we are...
GOG, stop reading my mind :/
