Excellent Submarine simulator, I'm a veteran of the old SSI games Silent Hunter, and this game is way better, the graphics are beautiful,and the sound effects are spot on,and the fun factor is great and very immersive and realistic, management of your crew is very important but you can set the difficulty so if you don't want to micromanage you don't have to, but if you do you can manage everything from your team to your subs fuel, torpedoes ECT, I mean keep in mind you do have your boring traveling long distances and all,but time compression makes it much better, but when you get into view of an enemy convoy and setting up for your torpedo strike is just amazing, now that it's a complete game, I'm having a blast with it, and you can take a really good tutorial that is easy to understand, so I definitely recommend it.
