For what it's worth, the game as-is is (marketed as) supposed to be a bare skeleton of how progression should work, with the grindy nature only as bad as it is because all the other content that's filling it out isn't in to hold it up.
There's supposed to be quests that result in discovering the boss you need to finish out the tier, that you find by doing other exploration stuff or something. Pixel costs are supposed to be ameliorated by building housing for NPC's and furnishing them with loot from your travels to have a pixel income apart from those pitiful pill containers and stabbing pokeymans. You're supposed to be able to turn a profit by setting up farms to grow excess food and trading the food at market. You're supposed to be able to plunder the surface dungeons for expensive loot to sell at trading posts or to boost the value of your NPC housing (and NPC vendors you house are supposed to scale their inventory based on the value of the decorations you make for them).
You're supposed to get tools each tier to make everything more fun and engaging. You're supposed to be getting random quests to fill out loot/money/resource concerns. Blah blah blah features blah. The colossal amount of stuff that's supposed to come in to alleviate all the problems the game has that... really isn't getting consistently worked on as though there's a plan to actually finish the game, is what's pissing people off and [RANT EXPUNGED].
Snow infantry is tier 1 you just have to kill dozens of animals for leather and build whatever crafting station. Also... there are asteroids in livable planetary atmospheres (sometimes) and asteroid fields in space. I think there's some confusion between the two.
...Asteroids in the sky, you mean?
Any indicators of that? That's new in my eye o-o
Though given the lack of update, that means I'm so outdated, its new.
Yeah I think most of the breathable planets have asteroids in the sky. Start on any given planet and build stairs out of dirt. Keep building. When you start to freeze you're almost there. Keep building. Place some fires. More dirt stairs. Asteroids. Do note that this is actually COLDER than asteroid fields IN SPEHSS so at some point you will need 4 campfires or a nanostove to stand directly on top of or you'll freeze almost instantly in any armor. They're also not as rich as the planet-sized asteroid fields IN SPEHSS.
Given that metal trees give... ordinary wood. Maybe.
I'll just assume that this game runs on Spongebob Squarepants logic.
I've seen some types of trees (on volcanic planets I think) that yielded "metal-coated" wood that was a different texture. They don't drop pinecones so the supply is limited.
