I'm trying to have SOME principles here. (-_-')
I want myself to earn money by game develpoment some day, there is nothing wrong about it. I also don't have anything against .rar. If it's better than the free .zip, sure, sell. It's totally ok. It's just because *points to some person who just got to know what .rar is* there still are people who don't know what a .rar is, so I try to use .zip when I "release my scripts and the demos of them". So I don't have to worry about these questions. Go with the flow. :=
