I think this is a fair assesment
From Metacritic
Eurogamer
"As a game, Silent Hunter 5 fails because the bugs and UI render it a chore. As a simulation, it fails because the bugs and UI render it ridiculous and incomplete. As a product, it's just overwhelming disrespectful to this long running series' fans. And finally, as one of the first games to receive Ubisoft's new copy protection, it's an embarrassment."
They gave it 50/100, I wouldn't even go that high personally.
