This one mention the graphics
The first thing that strikes you about Endless Ocean is the presentation. It’s awful right from the word go, from the front-end menus to sound effects. Take, for example, the graphics. They are terrible, even for the graphically anaemic Wii. Animations are stiff and wooden, textures are bland and lack detail, and aliasing is ludicrously salient.
If anyone is interesting in diving into a very relaxing slow pace game (PC) then I would recommend Silent hunter 4 and if you have a old PC then SH3. I can even read a book while playin.
