Before play
Choose one outcome (for example, understanding opportunity cost) and introduce the key vocabulary.
A teaching tool, not a textbook replacement
EOI connects world-knowledge questions to choices about resources, borrowing and negotiation. When students explain their decisions, the game becomes a springboard for deeper learning.

Practical classroom fit
These are proposed teaching formats, not official tested lesson packages. The full game can take longer than one class period; a short introduction uses a selected activity and a debrief.
01 / 15–20 MINUTES
Select a geography or economics question, let students justify answers and follow with a short research prompt.
02 / 45 MINUTES
Model a decision, play a limited demonstration round and discuss negotiation, resources and opportunity costs.
03 / EXTENDED SESSION
Use the full game format for 2–8 players per box, then connect decisions with your curriculum goals.
Curriculum connections
Suggested links to common subject areas. Always review the edition, actual cards and local curriculum before formal adoption.
| Classroom setting | Focus | Example discussion question |
|---|---|---|
| Social studies / geography | Countries, capitals, resources, world relationships | How does geography influence opportunity? |
| Economics / business | Auctions, incentives, budgets, debt and trade-offs | When is taking on debt a sensible decision? |
| Global perspectives / civics | Power, negotiation, cooperation and fairness | Who wins and who loses in an agreement? |
| Homeschool / enrichment | Research, discussion and comparative reasoning | What surprised us—and how can we verify it? |
A serious approach to game-based learning
Game-based activities are most useful when educators set clear objectives and ask students to interpret their choices. A session should include reflection, not just a winner.
Choose one outcome (for example, understanding opportunity cost) and introduce the key vocabulary.
Ask players to record a decision, what they gave up and why they made that choice.
Have students compare strategies and identify where the game simplifies complex real-world events.
Use an exit ticket: one fact learned, one economic choice explained and one question to research.

Questions schools ask
Not necessarily. Published full-game times vary widely. The 45-minute outline is a short teacher-led activity, not a claim that a complete game ends in one class.
The published age recommendation is 13+. Teachers should evaluate reading level, subject matter and suitability for their students.
One copy supports 2–8 individual players. Team formats or multiple sets are possibilities to trial; we do not claim those are official modes.
No. Ask about available resources, demonstration options, current inventory and shipping before promising a school programme.
Tell us your grade level, subject, country and preferred activity. We can discuss suitability, materials and availability.
