Fungibility - A Game of Identical Cards

Long time lurker, here. I don't generally post, as I don't often feel my ideas are really fit for general consumption, but my latest design is something special. I thought it would just be an exercise in experimental game design. I was as surprised as anyone else to discover that the game was actually playable - more than that, it's even fun.

The game I've come up with is currently called Fungibility, which is about as fitting a name as there could be: This card game uses 108 identical copies of a single card, and no other components.

From that improbable setup, I've managed to derive a business empire themed game with resource management, card drafting (yes, I know how that sounds), and adaptability, playable by 2-4 players in under an hour.

A barebones edition of the game is currently available, free to print-and-play, linked from the game's page on BGG, here:

Here's where the concept starts to really go off the rails: I have also designed 3 expansions for the above linked base game... but they add zero physical components. Instead, my intention is that any retail published version would have art elements required by the expansions, but the core rules would not reference these elements or explain their functions. Post release, I would then make the expansions freely available at regular intervals.

Of course, this all assumes the increasingly improbable scenario of a retail publisher actually being interested in the game, and willing to allow my "rolling upgrade" system of enhancing the game post-release.

So... thoughts? I do request that, anyone tempted to chime in with "sounds like every game would play exactly the same" or offer similar criticisms please read the rules prior to posting.
