I am and original owner of the game back in 12/6/2014 and Naval Action Sea Trials never should have been removed from the main game. NA Sea Trials is why I played the game. Naval Action: The Age of Sail was just a beautiful game and many streaming youtubers were on quite a bit it was NA Sea Trails that interested them and myself. We tested the first Ships in battle and Sailed on Calm and Stormy Seas. You worked your way up by grinding experience and obtain the next Ship. As in World of Warships your Ship may be sunk in a 25 vs 25 sea battle but it would still be available to you when the battle was complete. Naval Action: The Age of Sail and Naval Action Legends should be combined in the same game package and you have the choice to play OW or ST Legends.
