Huge patches that are ankle deep. Small patches that will last you till the heat death of the universe. Maybe the best or worst of both worlds. I suggest this since my current game miners are the slowest things in the universe so the big but low richness ones would be fine for me.
Also maybe some lottery, instead of fish, launching rocket with space science gives you a random item and part of pool are either op item that is guaranteed to break game or some item you use to 'win' the game. Idk.
