A friend of mine bought "U-Boot: The Board Game", and it looks pretty fucking glorious:
For scale, the little cardboard U-Boat is roughly 60cm in length.
You play with 4 guys, one is the captain, he gives orders, has the mission logbook, keeps track of the crew's fatigue and moral as well as resolving issues resulting from that. Also he's in charge of launching torpedos.
One is the navigator, he uses a map, rulers and a disc for angle measurements to plot a course as well as using another angle measurement disc to track ships if you make contact. The same player also is in charge of food, which he can use to boost morale.
The third player is the chief engineer, he repairs stuff and operates the throttle and the submersion aspects of the ship.
The last guy is the first officer, he uses an app on a Tablet or Smartphone, that will keep track of the ship's location, tells you when something happens (ie: when you get attacked by a plane or ship, what gets damaged and so on) . . . and this is where this whole glorious game fucking breaks apart.
Essentially, you have one guy playing a mediocre U-Boat sim on a smartphone, while three guys watch him do that and he occasionally tells you what's going on. He can't navigate without the maps from the navigator, but that's pretty much it for how much he has to rely on the other players. When the Captain (say) wants to launch a Torpedo, the First Officer hits a button on the app, which will ask whether every crewman is in position (ie: is the torpedo targeting computer manned, are enough people in the torpedo room etc), he hits okay, resolves the launch procedure and then taps on the launch button. This is the same, no matter what you resolve on the ship. Fire? The FO just taps a button to put it out and is asked whether everyone is in position, he hits yes and the app counts down a few seconds and the issue is resolved. Wanna dive? The app asks whether every crewman is in position and if so, it gets resolved. So, there's a few things outsoruced from the app that it could keep track (like moral and fatigue) which is put into a boardgame, but it's really not working anywhere near as well as it should.
There's also many issues with the game itself. Apparently, neither the app nor the manual does not tell you how fast your ship is on full, half or small speed.
When we played yesterday, we founda convoy with a destroyer and 2 cargo ships. We dived and moved in position to follow them, with the effect that they simply outran us (despite only making 6knots). We immediately came back to the surface and hit full throttle and followed on their course, but we didn't catch up. Some time later, we spotted another ship, tried to follow it on full throttle without being submerged, it outran us, despite it going only 7 knots. For some reason, the U-Boat in this game is slow as shit, might be a bug in the app.
Another weakness of the app is that you have to manually operate the Anti-Air guns and the deck canon in that app. While you do that, everything is still running in the background. So, say you're in a battle with an airplane. The First Officer will try to shoot it down while everyone else just sits idly by and watches until he's done. Sounds silly? Gets even worse. While he operates the guns, the ship gets damaged, but in order to check on that, the FO would have to switch away from the gun to the ship status screen to tell us what damages we just received, meanwhile, you're completely without a defense against the plane that proceeds to tear you apart.
The game is still in beta, so there is a lot of potential, but as of now, the boardgame aspect of the game feels like busywork while one player babysits the App way too much.
