I never explained this before, but I use a rarity system to rate my games that is used by Digital Press.

It is as follows:

* R0: Titles listed with a rarity of zero are simply games that were never released or require more research.

* R1: These are the items you can find or BUY anywhere. When you find a bunch of games, these WILL be in the pile.

* R2: You can find these titles just about anywhere, too, but they're slightly less common, perhaps in certain areas.

* R3: You'll find these items through the proper channels (other collectors!), not as common "on the street", but fairly common on the internet.

* R4: Things get a little harder here, as a title rated as such could have a lower production run, or other factors that pull it out of the common bin, but nowhere near rare. You can start calling titles from herein uncommon.

* R5: The hunt begins. Five are the kinds of item you have to look for, but definitely always in reach.

* R6: If you see a six or greater, at least one of us had a problem finding the title. You call this very uncommon if you so desire, or borderline rare.

* R7: Rare. A true collectible! Sevens and up representsome of the "hardest" games to find.

* R8: Consider these the items you'll never find by chance (except in those legendary lucky finds!).

* R9: The centerpiece of a collection make up the nines. If you ever hope to BUY one of these, prepare to write out a big check.

* R10: Not only is this the centerpiece of a collection, but a ten also means you could be holding a one-of-a-kind (certainly one of no more than a dozen or so) there - kind of like owning a 1952 Topps Mickey Mantle, or Issue #1 of DC's Action Comics.

so there it is, now you won't look confused when you see my ratings with games I buy. =P
