Students make strategic decisions each turn, seeing how their choices compare to actual historical events. Each turn advances the timeline with new challenges and opportunities.
Students can discuss potential actions with an AI tutor that uses the Socratic method - asking probing questions to deepen understanding rather than giving answers.
Teachers can review and provide targeted feedback on individual student actions before they're finalized, guiding learning while maintaining student agency.
The Overwatch dashboard lets teachers peek into any faction's progress, send messages, and intervene when needed - all without disrupting the student experience.
AI-generated benchmark runs show what historically accurate decisions look like, giving students a reference point to compare their strategic choices against.
Students work in groups representing different historical factions, experiencing the complex interplay of competing interests and limited information.
