ThatSoftwareGame is a web-based serious game for experiential learning in IT project management. It combines briefing and evaluation phases with a real-time simulation in which participants manage projects, personnel, time, risks, and emerging project problems. Research Snapshot 2026.1 provides a stable, citable description of a specific research-relevant state of the proprietary application. It corresponds to internal software version 1.2.8. The archive identifies the exact frontend and backend source revisions used for this snapshot and documents the principal functionality relevant to scientific publications and empirical evaluations. The proprietary source code, executable deployment artifacts, databases, credentials, and production configuration are not distributed with this archive. The source repositories remain private. The publicly running application may continue to evolve and may therefore differ from this snapshot.
