"Age" in this context meaning the period between having defeated certain bosses, e.g. bronze age after first boss but before defeating second boss and so forth.
My favorite age is stone age, before defeating Eikthyr. I like the simplicity of running around, foraging food and gathering resources off the ground. Having created the beginnings of your base and then gather more resources to update your stone/flint gear is peak comfy, thanks to the atmosphere of the meadows and the background music. It's incredibly relaxing and cozy, the meadows feels like a safe area where you can hunt and forage in relative peace – as long as you stay away from the Black Forest. I wish you had more to do in this stage of the game, without it becoming too complicated.
Anyone else like the first stage of the game? Or do you prefer the later stages, with more building blocks and increased complexity?
