The people who create their own gamemodes from scratch will feel more rewarded for their efforts and will actually learn useful things because it forces you to think by yourself and come up with the 'systems' in your own way rather than just copy and pasting or editing other peoples code. However, if other servers are more successful than yours when they have put fuck all hard work into it then it can get really frustrating and this must be what stops people from writing their own stuff.

Most people like to stick with what they know rather than learning a whole new system; even though it isn't that difficult to learn.
