Digital intercultural training tools play an important role in helping people to mediate cultural misunderstandings. In recent years, these tools were made to teach about specific cultures, but there has been little attention for the design of a tool to teach about differences across a wide range of cultures. In this work, we take the first steps to create a digital self-contained culture-general training tool. In the first part of the article, we focus on different aspects and methods of intercultural training. This information is then used in the second part to evaluate the effect of these different methods on the perception of behaviour in misunderstandings. We found that experiential and story-based approaches may lead to different perceptions of participants. In the third part, we expanded on these critical incidents, and incorporated virtual characters, to evaluate if experiential incidents in an embedded story can lead to an attribution of perceived differences in behaviour to specific differences in culture and to users becoming less judgemental of inappropriate behaviours by people from different cultures. The results suggest that the tool had some effect, but that a debriefing relating the general differences to specific instances would be beneficial.
