Yes & yes.
It's interesting to note this is the third guy to find these things, all came from South America. The first was a few months ago, someone on AA bought one copy of each along with alot of other NTSC games, and then he offered on the boards there. I don't know if he ever sold or not though.
Then a guy on ebay, who had at least 2 Ikaris & 3 Motorodeos, maybe more? He's kept one of each for his collection & sold 1 Ikari & 2 Motorodeos so far. He may have more to sell. His have been going for the same price that Matt was selling for this third guy. The third guy sent Matt 8 copies of each, Matt kept one set, then the other 7 he's working on selling now.
I'm not sure if there are any more of them out there or not, but Matt seems to think this guy bought everything the original owner had. So after these are gone, probably won't see anymore around.
It's alot of money to spend if these turn into common games 6 months from now.
I think though, maybe a few boxes of these were purchased from Atari back in the day for some shop in SA, and these are probably all that exist. Only time will tell.
I just didn't won't to miss out on them, if these do dry up again.
It's crazy to think that some of Ataris own could be so rare!
