This article focuses on the intersubjective process of meaning negotiation, through microgenetic analysis of Role-Playing Game sessions. We departed from the supposition that the analysis of I-other interactions, during that game, could put in evidence relevant aspects for the comprehension of the relation between intersubjectivity and otherness in interpersonal contexts. The results of the microgenetic analysis of the dialogues among the players showed the participation of important psychological processes in human development. In those processes, moments of tension and disquiet - typical of otherness relationships - were alternated with moments of convergence and sharing about the topics of the dialogue, as well as about the relational positions of the interlocutors.
