I heard that the game is literally unplayable if you don't have high-definition
-- the graphics become so dark that you can't see some of the paths you're supposed to take to complete the levels.
Players will have expected, at the very least, that Skull Island would look better than on other consoles, taking advantage of the better graphical and processing abilities of the 360.
But Ubisoft has warned that the opposite may be the case.
"We have a problem on the 360," said Mr Guillemot. "The screen is dark on some TVs and it totally changes the experience. When it's dark, you don't see where you have to go."
The Ubisoft boss said the team who made the game used certain settings on high-definition TV screens.
It did not occur to them that there would be a problem with standard televisions, which are what most people use to play console games.
