Hope you don't stop at biome modifiers and add stacking town and POI modifiers, plus some extra dynamic modifiers that change with stuff like weather, time, debuffs etc. You've got a wealth of content in the game. Shake things up a bit, give us more varied playthroughs, less inclusive lootlists so that everything isn't everywhere and long-term goals like the radiation zones you are planning. And stop playing Skyrim and play some Rimworld for god's sake MM 😛
