I propose Satisfactory, Foundry, Desynced, or Shapez 2.
None of them involve anime, through I think the robots in Foundry and Desynced look cute. All of them involve building things, and automating the building of things.
You don’t have many opportunities to grind in Reverse Collapse. The game is hard, though it mainly depends on your ability to strategize than raw numbers. For example, there’s one boss early on who’s completely unbeatable unless you can exploit her AI into running on some plants.
It’s a nifty little game where the protagonist and the player are treated as separate characters. Some girl found herself in an apocalyptic world, and the player appears as a disembodied voice to lend assistance. What I like about this one is that the protag has some Tales-esque skits to chat with the player directly.
