It must have been a somewhat dull first generation of stars and planets with only Hydrogen and Helium around.

On the other hand, giant stars explode after just a few million years so it didn't take long for other elements to appear.

The ratio of heavier elements to H & He is called metallicity, and it is a measurable characteristic of stars, which are classed into Type I (high metallicity) and Type II (low) populations. Low-metallicity Type II stars are generally older.

Nothing specific on what Type II stellar systems and planets would be like, though I'd suspect gas giants, generally.

I think they make up for their dullness by being absolutely massive–hundreds of solar masses, if not more.
