The Mines in Stardew Valley are an important part of the game, and one player's suggestion could meaningfully expand on the core concept. While farming is the primary gameplay loop in Stardew Valley, it's hardly the only way to make money, as fishing and mining provide an excellent source of income in the early game. Furthermore, exploring the Mines and the Skull Cavern is an excellent source of ore, a necessary material for upgrading the player's tools.
