A fair decision

Which one fits your escape room?

Consider ARC when you want
  • One system for games, native automation, devices, displays, diagnostics, and room resets
  • A broader mix of smart-home, industrial, stage-lighting, custom-prop, and Node-RED connections
  • A multi-room staff workflow with separate tools for building and operating games
  • A migration tool that turns an existing M3 story into a reviewable ARC starting point
Consider M3 when you want
  • The M3 Story, Prologue, and Epilogue model already matches how you build experiences
  • Your rooms rely on M3 custom C# scripting or custom HTML that you intend to keep
  • Your team is established in M3 and the cost and risk of changing outweigh a different workflow
  • The specific devices and integrations listed by M3 cover the rooms you plan to operate
