4. Seaman
Once you get over the games name, key concept, and gameplay, the cover art is just as ...unique. Instead of perhaps hiding the games title even a little bit, the developers put Seaman right in your face. A big sign with the words Caution Seaman, is going to catch anyone's attention, but perhaps for the wrong reasons or simply not the intended target audience. What else would you call a fish that has the face of a man?
