Atari 2600 R10 or 90+ rarity meter

these R10 games. its nearly close to impossible to find them sealed etc. what if you can get a R10 but in a loose condition without any manual or box and the cartridge seems dirty also.

Is it good to take it for 30$?

And i read somewhere about a Game Brain for the Atari 2600. any idea whats that.
Moreover i stumbled upon a game by the name of T.U.G. The Unkown game for the atari 2600. any idea what is it. i cant find its record anywhere on this site.

If you find a R10 in any condidion for 30 dollars you will wake up-its not gonna happen. By the way, some of those games dont have boxes, so a boxed collection is impossible. That would be Brain Games for the 2600, which is pretty common. Can you upload a pic of T.U.G.?

Also note the version, I know that the Atari Rarity Guides are currently only for NTSC games, some games that are rare fro NTSC may not be as rare or valuable for PAL

With Game Brain i was referring to this thing

Oh thats cool, its a splitter so you can change games with a flick of a switch. Kinda pointless actually.:cool:

and here is the unkown game thread

Atari 2600 T.U.G. THE UNKNOWN GAME game cartridge #20 - eBay (item 370239532071 end time Sep-02-09 04:07:11 PDT)

Buy it, I have never seen it, it may be really rare. Atariage dosen't have info on it.

ok thanks i will go for it

Seems like it was a prototype and then someone made 25 copies of it?

See this post in atariage:

Preorder: "The Unknown Game" by Datatech - AtariAge Forums

Yes that link surely explains it all. So you guys still think its worth buying ?

Its certainly an interesting item if you're into buying stuff like that I think it would b a nice addition to a collection.

On the other hand there are some people who collect only "official" games and dont bother with protos/homebrews

thanks . that was helpful .
