as i fear it,silent hunter 8 will be a 3-D movie on wich you can select "win-lose" at the beginning.
after that you sit back and view the game,sometimes you will be forced to add some upgrades(maybe they will include an "automatic upgrades") but your greatest worry will become that the pizza is delivered before your sub attacks a convoy!
after a beautifull fight(auto screenshots included),you will then be able to share the results on this forum in stunning 3-D(and for those with a better computer with smell of the sea and oil included).
some of the older generation will then shock the newagers with their stories about silent hunter 5 where you had to make every dicision yourself and could not let go of the mouse(mouse?what is a mouse?) while scanning the horizon without risking to miss an airplane...
