And I hit Wikipedia then go looking for primary sources online.... (lol!)
I mostly avoid books (even got rid of my full set of Britannicas with yearly updates) because old age makes reading a format where I can magnify with the tap of a button or the change of a font point size much easier. Sadly, for some good things, one must still dig into books as not everything goes digital (esp history books). That said, I do miss the enjoyment of tangible paper books.
The UWP provides a limited amount of information without a lot of context. It is 'neat' - I'll give you that. Most forms of coding of data can be interesting in that way also. But it lacks depth.
If that's what you prefer, there's nothing in any software product that generates systems (for instance) that threatens that use. For those that would use it, it could be useful.
I can't count the number of times my players, even after years of playing, have to ask me how to decode the PPP to identify which one is dexterity or education.... I've usually been asked to do any character sheets with STR END DEX (or was it STR DEX END? even I forget after 40 years of using it!) or the full attribute name (Strength, Endurance, Dexterity) in preference to having a UPP.
And there is a similarity with the UPP: I look at it, I know what some things are automatically, but I always have troubles with whether atmo 6 or 7 is standard no taint and in governments I can name (0 - family/none, 1-corporate, 2-direct democracy, 4-rep democracy, 5 feudal tech, 6-captive, 7 balkanized, 8 or 9 is bureaucracy, 10+ involve oligarchies and dictatorships.... but I'm sure that has mistakes and I know it has gaps). So I still need a decoding key to be certain.
Having a decent text representation, while less compact (again, not sure that's so critical in the days of computers), can present with clear english (or localizable) tags and thus be human readable without a decoding key.
This is one example, though it is fairly physical focused and not as rich as I'd like to see, but it is visual.
The Traveller version (book 3) (complete with planetary fractal maps - click on the planet in the table generated to see data)
Another from Starfinder:
Another without a lot of detail but visually interesting:
Yet another
Another that can be based off real stars
Planet Maker (somewhat buggy tweaky planet creator)
The tweaking is quite detailed.
Star system generation with an animation component
I have not seen a full implementation (maybe Heaven & Earth or Galactic?) for Book 6, World Builders, or World Tamers. Am I missing such a thing? And do any of them run without hte aid of ancient technology that makes the Model/1 seem amazing...? (modern OS)
