not sure what map you are referring too with the pegasus and orion comment, but this map screams forge to me:
really looks like cookie cutter pieces in the same style and design as much found in eden/empire.
This one:
It sure looks a little more complex, but Frankie also teased significant changes to Forge and the outside area really reminded of Orion and Pegasus in the footage. Sadly, it's once a gain a grey map, which looks pretty boring. Should be a little more colorful, if you ask me.
And yeah, your example also looks like something you could do in Forge.
