Marcus: Mistake #1 (selling legendary fish raw) caught me on my first play through. I caught a Golden Koi on Day 2 and sold it for 800 Gold. Later learned the cooked dish sells for 8,800. That single decision cost me 8,000 Gold and changed how I approach all rare items.
Lin: Mistake #3 (no co-op partner) is the silent killer. Solo players cap at ~60% of the gold/hr that duo players achieve. The first 2 weeks I played solo, I left 6,000 Gold on the table daily.
Sofia: #20 (Wiki checklist) is the meta-mistake. Players who follow any comprehensive daily checklist out-earn non-checklist players by 8,000+ Gold/day on average. It's not a single fix, it's the framework that prevents the other 19 mistakes.
