These ratings are intended to give an approximate guide to the relative scarcity of SMS games worldwide. They were compiled from the combined experience of several dedicated collectors and from tracking over 30,000 games sold on eBay over a six-month period.
While they are intended to be as accurate as possible, please note that they should be treated only as a guideline, especially in regards to the different regions - a European-based collector will naturally find European games much easier to find than American or Brazilian releases.

Also bear in mind that while some games may seem very hard to find, there are only a tiny number of titles that deserve serious expenditure. A patient collector can find 99% of all SMS games for £15 ($30) or less, and the vast majority of those will be under £5/$10.

353 Rarity figures for games being held in our database.

Key:
10	Reserved for unique items.
9	The rarest commercial SMS titles, any games rated 9 saw a very brief distribution in very limited areas. Unless you have the most extrordinary luck, you'll be shelling out big-time for these. And bragging about them afterwards.
8	Generally the rarest games that had a "proper" release, you'll find quite a few of the very late releases amongst the 8's. They often pull in big money on eBay, but occasional bargains can still be had. You can feel rightly chuffed if you find any of these in the wild.
7	Although "rare" is a horribly subjective word, you would probably be justified in applying it to any game rated 7 or above.
6	You won't see these every day, but you can be sure they'll turn up eventually. Still a nice find when they do!
5	Not rare enough to be "rare", but a lot less common than the "commons". In a move of startling originality, let's call these "uncommon".
4	Getting a little harder to find, possibly more so in certain areas than in others, these are still never really out of reach.
3	If you don't find these locally, you won't have to look far online - there's never a shortage on eBay.
2	You'll never need to look hard for these. They're probably clogging up the shelves of your local games emporium. Because the Master System sold much more poorly in the US than in Europe, '2' is the lowest rating for US releases.
1	You can't leave your house without tripping over a pile of these.
-	Game has not been released in this area.
