A key resource for the T-Crepe planet platform is an original open-source, authoring system for the creation of digital games called 'Choices with Consequences' or ‘ChoiCo’ games. These games are based on the idea of an avatar navigating amongst the diverse consequences of making choices in situations characterized by complex socio-scientific issues. For example, the demo game ‘Sustainable Textiles’ deals with the issue of making sustainable choices in smart-textile engineering.

Educators and students can play:

• existing ‘expert’ games, or/and
• new didactically ‘engineered’ games as a variation of an ‘expert’ game by changing specific parameters, and/or
• ‘half-baked’ games (i.e., games with intentional “bugs” to its original content and rules), aiming to challenge the players to modify or to extend it. While learners question, modify and improve a 'half-baked' game, they express and construct new knowledge about the game's underlying concept (e.g., empathy, entrepreneurship, etc).
