How does this compare...

To Dyson Sphere Program and Factorio?

I love both those games, especially Dyson Sphere because I like the scale and scope of building a Sphere around the sun.

Would I like this? What are the similarities and differences?

eh... Maybe, it's more a chill game, with zero pressure.
If you need something to push you forward, other than personal desire, I don't think you will like it it.

I'm not familiar with DSP, but comparing to Factorio:-

• Shapez is more relaxed: resources are infinite, there are no enemies, there is no time pressure, there is no specific game-winning goal beyond just completing all the milestones and tasks.
  
• Shapez is more abstract. Shapez 1 was completely so, but even Shapez 2 doesn't pretend to simulate any real world processes.
  
• The assembly process is 'white box' rather than 'black box'. In Factorio the recipes are predefined: an assembler 'somehow' turns iron plates into gears. In Shapez the effect of each machine is more fine-grained, and it is up to the player to figure out a combination of operations that turns raw materials into the desired product.

Overall, I would say that Factorio is primarily about logistics, with some puzzle elements to small-scale production line design, while Shapez is primarily a puzzle game, with logistics playing a very minor role.

I've got a few hundred hours in DSP, so I'll compare that. Many of the points Khagan made above related to Factorio are also relevant comparisons to DSP: Shapez 2 has no resource limit, no enemies, no time pressure, no machines that need a "recipe" of input items, and no real logistics challenges. Other points of comparison:

Like DSP:
-Both games have great soundtracks!
-Both games are pretty low-pressure, at least if you play DSP with no enemies.
-Lategame/endgame gameplay is self-defined. In DSP, most endgame gameplay seems to be either trying to design and build the sweetest looking Dyson Sphere you can or maxing out your logistics empire to build Universe Matrices (white cubes) as fast as possible. (Many other goals exist, but they seem less popular to me.) In Shapez 2, the guided gameplay runs out after 20-60 hours (depending on how aggressively you multi-task your factory) and after that the game generates random shapes for you to complete. In my understanding, many players then construct "Make Anything Machines" (MAM) which use the ingame automation tools to automate the analysis and production of the randomly generated shapes. The first ones were pretty easy shapes, but I assume they get more complex later. Designing a MAM doesn't really interest me, so thats's kind of where I stopped. In any case, both games imply, if not ask directly, that you should build some ultimate machine as an endgame goal.
-DSP and Shapez 2 both allow you to spend hours designing a factory that's *juuuussst* right. In my experience, Shapez 2's challenge is getting a factory or a sub-assembly of a factory optimized enough to fit onto a platform while still maintaining a full-belt throughput, while DSP gives you plenty of space but challenges you to design a transport network to adequately feed your factories with materials and energy. Similar enough; different focus.
Not like DSP:
-At first glance, the scale of Shapez 2 seems to be huge and infinite, just like DSP seems at first. But in my playthrough of Shapez 2, I doubt I operated in more than 20-25 sectors, since I found everything I needed was close enough to the hub. My opinion on this is probably effected by not attempting to build a MAM, so take it with a grain of salt.
-No space ships in Shapez 2, sadly. The graphics give Shapez 2 a space-y vibe, but to me its more like "what if Tron had outer space?" instead of DSP's star systems you can fly through. And there's no cute mecha in Shapez 2. :(

And of course, all of this could change, since the game is in early access still and the dev team seems intent on adding player-requested features regularly. Well this post got huge fast. I hope you enjoy Shapez 2, I sure do! Cheers!
