lol didnt want to start an argument just wanted to point out that you should allow folks to e-mail you for permission to use your pack in a commercial project, that they should is only common courtesy

Actually I dont even think butters was asking to use it commercial only if he could use it outside of FPSC.
I think you are doing nothing wrong in making your pack non-commercial only but think you should allow folks to do it if they request it after all no one should ask unless they actually have a game going out for sale or their game appears to have commercial appeal, that is, its pretty stunning or at an advanced stage, all the same I actually reckon its ok to give permission to someone who says they intend to make a commercial game, not all will make it.
I would ask that folks apply for permission with a link to their game so you can see if its worth your while.
I can also understand that folks wouldnt want to start a geme design and then be told they cant use it commercial, but I am sure you can tell most of the members who have been around for more than a short time they could go ahead.
I allow most folks who ask for permission to use my stuff in commercial games, in fact dont think I have ever said no to anyone, thing is I have no problems with it, but its nice to be asked first
I really apologise for this didnt mean for your thread to be ruined with complaints, its a really generous pack and great quality.
