There's a mass and temperature difference between gas giants and brown dwarf stars. The cutoff is whether the object in question has any fusion going on at all. At about 13x Jupiter mass it's big enough to fuse deuterium, and at 65x it can fuse lithium. If it's massive enough to fuse hydrogen, you've crossed into Red Dwarf territory (oh smeg!).

No form of sustained fusion has ever been detected within Jupiter, so it's not a brown dwarf, just a gas giant planet.

Actually, there were a few arcade titles following the 80's crash offered advantages if you chipped in more coinage. Cyberball 2072 would sometimes give you the option to buy improved team performance or enhanced players between quarters. And I seem to recall Xybots offering extra in-game currency for tokens. Thankfully the trend never caught on back then.

You want to offer a bunch of impressionable young people, most of whom are accumulating large amounts of debt, the opportunity to learn as much as they can about the computer security infrastructure of the country. While they do this, we're not paying them a cent or giving them any guarantees regarding future employment, further increasing their financial insecurity in the present and the future, as well as exploiting whatever sense of loyalty they might feel for their country for the purpose of reducing government labor costs.

What could possibly go wrong?

I doubt a 15 million year old universe would have been little more than atomic soup. Water may have existed, but not as we know it. It takes more than 15 million years for a star to form and blow up, where would you have gotten enough heavy elements for a planet to arise? :)

That's not quite accurate. Heavier radioactive elements would have come from supernovas, which only occur in stars much more massive than our own. The more massive the star, the higher its luminosity and the shorter its lifespan. Some of the most massive stars we've found will spend (or have spent) less than 100,000 years on the main sequence before expanding into supergiants and exploding as supernovae. So there's plenty of time for nucelosynthesis over that 15 million year span.

That's the mass threshold for deuterium fusion. No fusion = planet, deuterium fusion = brown dwarf, hydrogen fusion = main sequence star.

So at 11 Jovian masses, the planet is close, but not quite big enough to reach brown dwarf status.

This is now. Later is later.
