If you could create a biome (evil, good or neutral/spreads ,doesn't spread) in Terraria, how would it look like? (Your art is amazing btw.)
There really isn’t much that I’d want for in Terraria except for embellishments to what’s already there, since my favorite environmental archetypes are pretty much covered (snow/ice, crystal, body horror. It would be nice if there were an overworld crystal biome variant with actual crystal trees; maybe they’d be alternate tree sprites for the Hallow). Other things might be difficult to pull off at Terraria’s sprite resolution constraints, for instance, Giger-style sleek alien biotech. which might make a nice Underworld alternate.
Maybe a more alien or surreal-celestial inspired sky-island alternate would be neat, or underground magic-tech vaults (more of a mini-dungeon than a biome). Sort of like steampunk, but on the magic side. Think Engine of the Makers or Spark of Imagination in Ulduar from WoW.
