I really love that they're attempting to encourage exploration with the mob variants and biome specific blocks. but hear me out. it's not enough, I can't remember who said it, but changing the spawn rates of the ores and mobs per biome would really encourage exploration, similar to the Badlands gold generation but more subtle. I just feel like once I have all of the wood types in the game, then I'm done. and beyond that there's not much to explore for. idk just a thought, what do you think?
