Carrier Command by Bohemia Interactive. At first I was disappointed with this. I mean, if it was me that made this, I would have made it more like the Silent Hunter series or something. This is a bit arcady and simple, but as I've put some hours into it, I actually like it quite a bit. It's pretty fun and challenging to play, and gets more interesting the further you get into the campaign. The box cover from the original from 1988.
