  We build off the game, NimG to create a version named Neighboring Nim. By
reducing from Geography, we show that this game is PSPACE-hard. The games
created by the reduction share strong similarities with Undirected (Vertex)
Geography and regular Nim, both of which are in P. We show how to construct
PSPACE-complete versions with nim heaps *1 and *2. This application of graphs
can be used as a form of game sum with any games, not only Nim.
