I'm there as well. I've restarted twice, though neither was with any intent to actually go all the way to the end. I finished project assembly in 1.0, and then when 1.1 and 1.2 rolled around, I mainly just wanted to see what I could do with the new things that were added, optimize a bit more from lessons learned, try out the randomizer, etc.

This DLC seems like a great opportunity to take another solid stab at the game for the long haul. Learning the ins and outs of the new environment, buildings, resources, and so on.
