In this paper we describe the C generation system from the Universidad Nacional de Córdoba (Argentina) as embodied during the 2011 GIVE 2.5 challenge. The C system has two distinguishing characteristics. First, its navigation and referring strategies are based on the area visible to the player, making the system independent of GIVE's internal representation of areas (such as rooms). As a result, the system portability to other virtual environments is enhanced. Second, the system adapts classical grounding models to the task of instruction giving in virtual worlds. The simple grounding processes implemented (for referents, game concepts and game progress) seem to have an impact on the evaluation results.
