Grinding Gear Games’ Path of Exile has a lot to offer hack and slash enthusiasts.  Blending aspects of Diablo II with concepts similar to the Final Fantasy sphere grid and Materia system, Path of Exile brings some other exciting features to the genre in the form of what can only be called “extreme” item customization and optimization.  Surprisingly enough, it succeeds at offering all of its action RPG content completely free, relying on contributions in exchange for cosmetics.
