I'm wondering if it would run on my netbook (1.6Ghz). I tried the fixed demo and all I get is a black screen with a mouse cursor. It will terminate if I hit esc a couple times.

Man. I’d bet that this is another screen resolution thing. Rubicon isn’t doing anything particularly strenuous or taxing. The fixed one just looks for the best out of a couple preset screen resolutions that works and uses that. I’ll try and throw together a fix that will allow you to override it and run it at whatever resolution you want.

So… basically I’m using you guys and the demo as an alpha test? This is good for me. It’ll let me iron out these rather game-breaking compatibility issues that come up from running on a variety of different machines that are just almost impossible to simulate by yourself. Thanks 1000x for your patience, bug reports like this will make the game stronger in the end.
