I’ve learned so much from every faucet of life (not just the military or college) and games have taught me so much of value over the years. Stardew Valley, Subnautica, or even Runescape are a few of the staples I enjoyed which all share similar themes of community and learning to grow/build in your environment with the gear you have.
In the real world it may not be as simple as trading in goods through a magic bin that generates money.
