Just as an FYI (and a barometer for rarity) my copy of Edtris was number 203 (purchased in May of 1999 I think). I am not sure how many copies sold after, but I would gladly part with this now one of a kind personally numbered collectible for the right price. j/k
I have to agree that eventually they will be collectible, but never really valuable. I would think that most people buying homebrew atari 2600 games in the 90's would most likely hang on to them for the long haul. Therefore getting one could suddenly become tricky.
Randy was very helpful and a great resource for the hobby, I was disappointed to hear he was no longer providing this service. I have no idea who is right and wrong, but I wish him the best if he is reading this.
