Well, got my copy here today in the UK courtesy of shopto.com and so far I'm totally blown away, so far the level of detail and immersion is superb, THIS is what I personally wanted from a world war 2 Atlantic submarine simulation.
I'm sure that after a few mods have been added by the talented people here this game could be made even better than it already is in terms of historical accuracy etc.
I defy anyone not to go 'wow' when they first set foot in the command room of a VII or not be impressed the first time you sail into Kiel or stick an eel into an unsuspecting polish merchant, well you get the drift.
Also it was nice to see Neal and the people here at subsim getting an honourable mention in the credits, a very nice touch from a very talented dev team who have done sh5 proud.
from me!
