There’s a ton to do in the setting.

At the top end, there’s the Lansraad and political maneuverings between Great Houses. There’s the Guild and the Bene Gessarit. There’s the Ix. All the way down to foot soldiers and spies and intrigue in the various house wars going on at any given time.

Honestly, Fading Suns was fantastic, and highlights some of what you can do with Dune.
