  i would say Yes. There’s a reason it costs so much!
  To be honest though, I’d be bamboozled just trying to build a calculator, let alone a whole computer game system!

  Yes. The main difficulty is the production of affordable blue, or ultraviolet, lasers which are used to read the BluRay discs. The latest computer games and HD movies need much more information than previously, more than can be fit onto a DVD. This required a new way of putting data on a disc.
  
  DVD and Bluray discs store information as a series of troughs |_| and the lasers read the pattern of these troughs to understand what they are looking at. The size of the trough is restricted by the wavelength of the laser light looking at it, the trough cannot be smaller than the wavelength.
  
  DVDs use a red laser with a wavelength of 650 nm (650 billionths of a metre) which is small and allows for many giga bytes (GB) of data to be stored on a disc. Lasers used in PS3 and other Bluray players, however, have a wavelength of just 405 nm! This means that the same format Bluray discs can hold 650/405 = 1.6 times the data of a DVD. This plus new techniques of reading multiple layers made the HD movies and PS3 games possible.

  I would imagine it is. I think making any computers seems hard!

  I think I’d find it incredibly hard!!! Though Sony (is that who makes them?) probably make thousands of them a day!
