0	Never Released Titles and Vaporware
1	Available everywhere; where games are, this is.
2	Slightly harder to find. Possibly have to drive around town to find it.
3	Not common on the street but still easy to get. Not in Target or Walmart, but obtainable.
4	Harder to get; lower production runs. They aren't too pricey when you find them
5	Probably need to eBay to get this - and you'll pay a premiium
6	Very uncommon - we've probably had problems finding it ourselves
7	Rare - very hard to find anywhere; even eBay.
8	Items you'll only find by chance. Very rare.
9	Good luck with that. If you do find one, write a big check.
10	The thing of legend - possibly only a handful available - maybe even one of a kind.
