Steelbook will give no information on the numbers of any steelbook produced as it is 'client confidential'
I do believe that some become mythically rare - for example Mirror's Edge is regarded as one of the 'grails' yet comes up for sale far more frequently that, for example, Saints Row 2 G2 but is that because sellers knwo they are going to get a good price on it
The really rare ones are the ones genuinely produced in limited numbers - single country exclusives etc. - AC11 stickerbook Spain - and that is made more valaubel by the fact that Assassins Creed is a highly collectible game with a passionate following
Mirror's Edge is, in fact, a great game and a stunning steelbook as well
I personally love steelbooks full stop - many of them works of art and a pleasure to own - but the ones I treasure the best are the games I like the most though exceptions are Need for Speed Undercover - visually stunning as well as rare
Less and less limited runs are being produced since they are expensive without the advantage of volume sales and manufacturers use steelbooks to drive preorders so the more the merrier! Restricting numbers is only really an advantage to resellers as it is hard to presell a game at a significantly higher margin and, even if a manuafacturer did, they would make more profit overall by selling greater numbers at a smaller margin...
Any road up - I for one am a steel fanatic and also enjoy the challenge of finding the truly rare ones!
