As a published RPG product, it predates the other things for which I'm known (including the d30 DM Companion, the otherwise first of my published products). It has been available as a free PDF download (direct from this link) and in print-on-demand from Lulu.com.
Well... some time over the last few days, the free downloads of The System from my MediaFire link surpassed the 9,000 mark (which does not include downloads from co-located downloads, like the one at 1KM1KT).
If you've never heard of The System, here's the topline overview... I originally wrote/designed this in late 1985/early 1986 (when I was about 16 years old) before other universal role playing systems were available on the market. As I was getting ready to playtest it with my friends, a guy in our gaming group brought in a copy of the (then) newly-released GURPS, and I shelved my system in the disappointment that comes with having someone beat you to the punch. In 2011, I "rescued the from oblivion" (that is, I scanned the old daisy-wheel printed version that came from my dad's word processor at work), gave it a (very) quick polish to the ruleset, and typeset it with a decidedly retro (1st generation) RPG feel to it.
As stated previously, I'm quite willing to admit the game has its flaws... I mean, c'mon, I was 16 or so when I wrote it. (e.g., there is a very convoluted constitution-to-hit-point system, and there is an innovative but ultimately ill-conceived initiative and movement tracking system, and while it purports to handle supers among its genres, I can't claim that it actually scales to reflect the expanse of power levels between the weakest and strongest heroes). But over time, I have more and more appreciation for the fact that it uses d6s only, and led to some underlying things that Welbo and I would like to see become part of a "2nd Edition" of The System. (Should we ever get back to it, but may something it takes us 10 or more years to complete.)
