But let's take games like Snipperclips or The Witch and the Hundred Knights 2, only about 25000 sold since February/March. Those numbers are awful.
Witch and the Hundred Knights 2 bombed indeed, god knows what NIS was thinking with that one considering the first one wasn't really a success either. Then again NIS doesn't have many successful franchise outside of Disgaea (which isn't even popular anymore in Japan).
Chart doesn't include digital sales outside of download cards so Snipperclips probably sold more than that.
