I am digging into the Dune core rules. Dune uses two levels of play. These are called Architect and Agent.
Agent level is where you are playing your PC in the thick of the action, as you would expect in a typical sci-fi RPG.
Architects is a more top-down level, where the players get to manipulate forces, at a more strategic level.
This is reminiscent of Legacy by UFO Press. It has a Zoom mechanic that lets you zoom in to your individual character to play scenes, but also zoom out to manipulate spies and armies.
I haven’t finished reading the rules yet, so I am not sure how this is going to interact with any solo rules. This two-level play is the most unique feature I have found so far.
