Latter day TGS dev here.  The logo at the top is my juvenile photoshop work!  A couple friend and I liked TGS v2 enough that we made it our own and kept streamlining and working on it: stripping out useless items and shops, trying to balance skills, improving the map design, etc.  The real fun playing was trying to find really synergistic hero builds, then trying to find counters to them.  But it was always a challenge to get enough players with experience.
