Hi. I'm looking for single-player naval simulations or rather games and flight too, that have single-player campaign or free-style levels, open sea, etc. In terms of visuals and gameplay similar to World of Warships or a lot better. But the most important thing that I would like in such a game is to play as German. I would like some recommendations but only if a game has German full single-player campaign, or at least open sea customizable missions.
