This one is probably outside of my expertice to make (although I'm willing to give it a shot with a little guidance), but I was thinking about how science is the only resource with no use at all near the endgame. Once you research the last tech it serves no purpose at all. My thought was to make an improvement kind of like the bio-converter which allows food to serve a useful purpose after all population slots are filled in a system. In a simliar vein, something like a "Dust Synthesizer" could make use of excess science once every tech has been researched to convert it into dust at perhaps some arbitrary rate (50%, 25%, etc), whatever seems reasonable. Alternatively since dust, unlike the production of a bio-converter, is an empire wide resource, this function could be made into a final tech that requires all of the "Endless" techs to have been researched first. Not quite sure how one would go about implimenting this sort of thing.

science victory is for casuals.
but yeah, the availability of techs should be a value of it's own.
Sole situation of conversion of science output to dust can be observed among one of Lumeris quest  infinite queue system output conversion options.

Did you post it anywhere or just make it for personal use? I'd be interested in seeing it.

I don't think science victory is for casuals. It is actually quite difficult to win.

Initially for personal use, but I was going to post it eventually.
