I think it has done both for me, in the ways of writing old stories and such it gives me ideas to how to throw things into a story idea. Or to make a story from a character I love so much. But in ways it hasnt done much good for the fact of writers block sitting there within writing a story, whereas roleplay you have someone on the other end to help. But either way, I think its done more good than bad. Its given me the ability to pull my creativity from wherever it seems to hide no matter which Im planning on doing.
