Combinatorial game theory in the form of two-player, win-move games have played an important historical role in developing formal argumentation, logic programming semantics and non-monotonic reasoning, database query languages, and more recently, data provenance. While connected originally through win-move games, formal argumentation theory and the study of query languages have largely separated from their historical connections, following their own paths with significant research results and tools. This paper touches on this history and highlights how the use of a single, non-stratified, logic programming rule within these two communities continues to connect many of their underlying approaches today, arguing that a potential fruitful line of research may exist by reconnecting the approaches, in a so-called “family reunion,” where results in each community may be directly transferable to the other.
