As a patient person, you also might give submarine sims a shot, as they do require time and patience. One of the VERY best sub-sims WAS Fast Attack by Sierra, but they did'nt do much beyond getting the game on the market, and then simply "forgot" about it. One that I have is Sub-Command...a VERY time intensive game with quite a steep learning curve. I had the origional Harpoon at one time, and that was very fun yet without such a steep curve. Best luck and weigh anchor!
