The game is still very buggy and large and many useful features of previous versions are no longer vorhaden. The game guide is not intuitive, a handbook which answers hardly a question, a stupid team management (when the same man for the 5th time must ask the same question about his wife to get the same answer zustärken only to the morality, the bored not only it is stupid ...), missing and false details (type VII / c in 1939, where are the external 2 torpedoes ?, etc.), etc., etc. The attempt aufzuhübschen the GUI with modern instruments for me in a Simulation, which claims to be realistic, also misplaced.
Not to mention having to of the need while playing have an Internet connection (No, not because it is a Onlne game, but of license protection reasons, Thank Your hacker !!!). This also makes it even less attractive (no, I'll pay at the hotel not expensive internet connection to SH 5 to speielen).
One may look around in the UBI forum SH 5 or Subsim to learn all Patzer this version. This is beyond the scope here.
Only about MOD's can (laboriously) bring some things to the fore again, you really missed during the game.
