Space Instigators is brilliant, just brilliant. Chris managed to do what I sort of fantasized about doing through my hack of Space Invaders. In fact, I think I'm going to put a link on my webpage suggesting people interested in my hack of SI check out his real SI instead. I am just thrilled and can't wait till I can order one online without Paypal.
As for XYPE, I have never thought of it as a 'club', more of a tongue in cheek 'company' like Ebivision. I had such a 'company' when I was a kid; we called it Nostafavision and I don't believe we ever actually released anything.
But seriously... Not everyone writing a random first person shooter in their basement would expect id Software to call them up and invite them to join id. I as an infrequent Atari programmer sure don't expect XYPE to do the same, though I hope to entice them to one day. But regardless of how it makes you feel - to date, all of the games under their name have been top notch, better than most actual companies trying to make money off of the Atari in its day. They are certainly not the only great 2600 programmers out there, but I bow before their mad skills and unfailing desire to help us all out on the Stella list.
