I suggested a new biome last year. It was filled with nectar shrapnel shoots, red hot poker plants, hot springs among metallic grid ruins and electrical storm-filled canyons. The suggestion was for a board game that my family played.
Now, Tynan hasn't proposed any new advanced civilization ruins map. At this point who knows what he wants to do with Rimworld? Could we face a map where colonists can't disassemble new, rare metals foreign to Earth? I think the question is how to deal with family members having sometimes terminal neurotoxicity. Could we even find a cure? There could even be particle fluidity problems among hot spring pumps.
Sounds like something that belongs in my thread here (https://ludeon.com/forums/index.php?topic=17103.0).
