The present Report (D2.1) is the result of tasks 2.1, 2.2 and 2.3 conducted in work package 2 (WP2) - State-of-the-art and Good Practices. It aims to contribute to theoretical and empirical knowledge on game jams and game-making co-creation practices among Cultural Heritage Institutions (CHI), Creative Industries (CI), Higher Education Institutions (HEI), and Youth. Regarding the Design-based research (DBR) model, the WP2 is part of phase 1: Analysis and Exploration. Following the PRISMA 2020 method, a systematic literature review (SLR) was conducted to answer the following research questions: a) Is there, in sources, a conceptualisation of cultural game jam?; b) what processes and tools are available and researched in game- making and game jams with youth participation?; c) who are the main stakeholders and participants?; d) are Innovation frameworks presented in sources?; and e) are culture and values embedded in game jams? A total of 68 articles were included in the review: 37 articles from the scientific databases and 31 from external sources. For the review, a coding guide was created in a top-down approach, with the participation of all partners involved in WP2 – Task 2.2. The analysis was conducted using NVivo 14 software with no automation. The Method, Results and Discussion are presented in the following sections.
