Some links that 404 I used internet archive. I suppose speculating on products that weren't sold is pointless. I've seen a bit of preview on the el raja key archive (enough to purchase a DVD). Zeitgeist can still be purchased on drivethru as can Dave's First Fantasy:
https://www.drivethrurpg.com/m/product/232776. I'll probably pick those up to peruse and compare.
Wow! I didn't realize code monkey was still hanging. I honestly thought it was gone. I'll pick up their random generator. I recall when 3.0 had s demo disc that support sort of went to code monkey but wayback looks pretty muddled up. Its sad 3.0-.5 didn't have that demo turned into a full Core Rules 3.0-.5 set to continue the tradition. I still fire it up once in a while fir nostalgia.
I'll look around as you suggested.
Cheers.
