Dune board game - two players (son vs. dad), quick playthrough and how to play

We just received our copy of Dune and this is a quick playthrough with two players. Dune is best enjoyed with more players; this is just a quick run and we explained most of the rules for the basic game. Son vs. Dad, a battle to the last treachery. EDIT: we made a mistake during the first battle, the Harkonnen player (son) should not have lost any troops since he won by using a traitor.
