What packages should be free on the Unity Asset Store?

Hi, We are a team of developers that think many things in life should be free and open source. So, if you could wave a wand and magically turn one of the following packages free, which one would it be: 1) Fantasy GUI pack (normally $15) 2) PlayMaker (normally $95) 3) Asset Hunter (normally $10) 4) Behavior Designer (normally $65) 5) Highlight Glow System (normally $15) 6) Universal sound FX (normally $20) 7) Energy Bar Toolkit (normally $30) WARNING: Your wish might come true so be careful! About us: our open source and free packages can be found on the asset store and on Github. I don't want to post links to avoid self-promotion so let's just say that if you google "unity open source framework" you will find us.
