R0: titles listed with a rarity of zero are simply games that were never released or require more research on our side. All rumor mill titles and current gen systems sport zeros.
R1:These are 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, they are just slightly less common, perhaps in certain areas.
R3: You'll find these items throughout 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 here on out as Uncommon.
R5: The hunt begins. Five are the kinds of items you have to look for, but definately always in reach.
R6: If you see a six or greater, atleast one of us had a problem finding this title. You can call this VERY UNCOMMON and if you so desire BORDERLINE RARE.
R7: RARE. A true collectable! Sevens up represent the hardest 25% of games listed in this guide.
R8: We consider these items you'll never find by chance (except in those legendary lucky finds). There are a few eights that we havn't gotten our grubby little hands on... yet.
R9: The centerpieces of a collection make up the nines. If you even hope to buy one of these, prepare to write out a BIG check.
R10: Not only is this a centerpiece of a collection, but tens mean that you could be holding a one of a kind (certainly just one of a handfull). Kind of like holding a 1953 Mickey Mantle or an Action Comics #1.
Note that a 2 for the Atari 2600 should be just as easy or hard to find as a 2 on the NeoGeo AES. It's all relative across systems, not within them.
