The purpose of video game tutorials is to help players easily understand new game mechanics and thereby facilitate chances of early engagement with the main contents of one’s game. The mobile game market (i.e., phones and tablets) faces important retention issues caused by a high number of players who abandon games permanently within 24 h of downloading them. A laboratory experiment with 40 players tested how tutorial presence and player expertise impact on users’ psychophysiological states and continuous-use intentions (CUIs). The results suggest that in a simple game context, tutorials have a positive impact on non-expert players’ perceived state of flow and have no effect on expert players’ perceived flow. The results also suggest that flow has a positive impact on CUIs for both experts and non-experts. The theoretical contributions and managerial implications of these results are discussed.

In the French West Indies, and particularly in Guadeloupe, agricultural policies mainly support the banana and sugarcane export sectors. However, driven by consumer demand, policy-makers are increasingly interested in developing local and agroecological food systems. Plantain (Musa spp., AAB), cultivated by a wide range of farmers, plays a key role in the diversification of local production and food systems, contributing to food security. However, important gaps in knowledge about plantain cropping systems are hindering the understanding of their contribution to the agroecological transition of farms. Farmers are also requesting more guidance from technical advisers and research. The aim of the work, presented in this article, was to co-design agroecological plantain cropping systems with farmers in order to fill this knowledge gap and to support local food systems. The co-design process was based on the characterization of the diversity of plantain farming systems, the evaluation of changes in practices implemented between 2017 and 2019, and the co-design of a system experiment. We identified six types of plantain farming systems defined by the role of plantain in the production strategy of the farm and a gradient of agroecology in plantain management practices. Our results also show progress toward agroecology between 2017 and 2019. Four innovative plantain cropping systems were designed based on a combination of existing knowledge held by farmers from the six types of farming systems. These results confirm that plantain cropping systems are contributing to the agroecological transition of farms in Guadeloupe and highlight that there are multiple possible agroecological transition pathways for plantain farmers. These results also provide a concrete example of integration of academic and non-academic knowledge for the co-design of agroecological systems.
