Ship Simulator would be considered by the masses to be a rather dull game as it stands now, when looking at SS08. Not that many people, especially inland, would have an interest in a game only about piloting a ship around, especially with a ship and environment selection that small. Many people, however, are suckers for pop culture! Stick something famous into a game and it tends to sell it, just look at the console games! Putting in a gimmick like the inanimate star of the highest grossing film of all time and at least a few dedicated fans are bound to notice. Those people buying the game helps sales, which gives VStep more money, which, in the long run, is what a company is all about. By the time they realize that it's perhaps only good for looking at, they've already tossed the money down.
