A little offtopic: What's with all those amazing chinese games recently? (completely subjective opinions)
Genshin Impact - milion times better Zelda: BOTW (not devaluing early zeldas)
Amazing Cultivation Simulator - better, more interesting Rimworld
DSP (haven't played yet) - does it have what needs to stand against Factorio? I know fighting local fauna is planned, is it going to be as extensible through mods as Pixelated Heroin (Factorio) is?
I too have noticed an uptick in Chinese developed games that really hit the sweet spot for me. To add to your list, Gunfire is a compelling (though simple) rogue-lite FPS that really nails the formula.
And that's it - these games are
formulaic. They all feel like a mish-mash of previously successful games in the genre. I hesistate to call this dev style unoriginal, but in some cases it really feels that way. In other cases, it's a serious refinement and polish of previous mechanics, and I currently am enjoying DSP far more than I ever enjoyed Factorio. I honestly think there is going to be more and more examples of Chinese developed games that overshadow their western inspirations. While I bounced off Amazing Cultivation Simulator, I think that is the closest we have gotten to a DF level of mechanical depth, so I hope to see more like that.
As far as DSP goes, it's got less tweaking and fiddling to deal with, which I never particularly enjoyed, and more glitz and a much more compelling end goal than uh 'launch the rocket' which we all know is just a convoluted way to say, '
I'm bored and want to restart.'
It sort of lacks the granularity of Factorio, and you find yourself with fewer options for tweaking and processing. On the other hand, without so many options, there is less to get wrong, and your prod train tends to stay simple enough I feel safe destroying everything and starting all over - a thing I never found myself doing in Factorio due to the annoyances involved.
As others have said, the game's stability and speed is impressive. The game kind of feels like how the Spore endgame should have gone - beautiful, scaled-down planets as resource containers, and a wide open space frontier where you can
Manifest Destiny your way to material dominance. I haven't played enough to experience the variety in planet forms, though honestly nothing will impress me there after playing No Man's Sky, so I'm just hoping for a a mixed set of generation parameters that result in planets that are, if not necessarily unique to look at, unique to design your base on.
Tech tree is deep enough you have to zoom out to see it all, and that's always a win in my book!
