I would like more reasons to return to early biomes besides getting basic resources, the black forest is my favorite place in valheim and the meadows as well. It would be cool if there were special dungeons that are too difficult in the beginning that you can return to later on, maybe with mini bosses. Also, the mine/smelt grind gets pretty repetitive, and with building being such a big part of the game, what if in a later biome, you are required to sleep in the biome, triggering a dream world to fight or aquire something in. To do so would require building a house with a bed and such. At the very least, some more creative ways to aquire resources.
