Lucky Luke - the man who draws faster than his own shadow. If you don't know this guy, leave this site now. Seriously - we don't want you here! Stop reading and go away!
So now that we've got rid of those non-cultured morons, let's talk about the game. It's about Lucky Luke helping a railroad to be built. Not sure whether this is supposed to be based on a particular comic. Could either be Des Rails Sur La Prairie (using the original titles here, because I'm not sure about English ones) or Nitroglycerine, with the latter being the more likely candidate, because the first ones predates the introduction of the Dalton brothers into the line. Then again, the similarities with the latter are fairly limited.
