|NBA Elite 11 is considered the holy grail of the PS3|
According to www.pricecharting.com
"For 2011 Electronic Arts tried to revamp their basketball franchise from NBA Live to NBA Elite. Elite 11 was supposed to be released in time for the 2011 season but it was officially cancelled November 2010 after numerous glitches and delays. EA had sent samples to some retailers but not every copy was returned after cancelation. So far only eight copies have surfaced, which makes it the rarest game on this list but the exact number of copies in existance isn't known."
The game currently sells for about 1000$ used, and between 2 and 3k for a sealed copy.
