This may be the first review of an app Ive ever written...Pacific Fleet is so good that I feel its my duty to spread the word. As others have said, the graphics, realism and attention to detail are terrific. And the variety of scenarios, vessels and escorts is great. One thing I want to make clear: the island battles are really not all that difficult once you figure out how to effectively bring naval gunfire (or close air support) to land-based enemy targets. Yes, the island battles are a bit non-intuitive and there is a learning curve, but thats part of the fun of the game. Im not a gamer by any means but once I got the hang of the island battles, theyre actually quite easy. Also I recommend going through each of the 40+ scenarios JUST with the submarine, then go back and add additional escorts and try the battles again (or simply start a new game). This way you will develop an excellent understanding of enemy tactics... and using just the sub is arguably the most challenging way to play the game. Lastly, there are a few useful player guides out there, just do a search.
