The sword fight is great conceptually and fits nicely to the pirate theme of the game. Execution wise it was frustrating. I am not a big fan of games introducing new game-play or combat mechanic at the very end of the game. Like melee encounters early in the game. It is really hit and miss. You think its a quick time event but it isn't. One reasons why it could be justified is that it creates tension for Nathan to use a weapon he has not used before. Maybe Nathan and Sam should had a mock sword duel when they were kids or after they arrived to the island as a tutorial.
