@Eiwynn I did an open beta. Any and all were welcome. It worked out pretty well. People contributed positively.
The only restriction I had was that, if you had a line of text you disagreed with or a bug you’d discovered, please record a snippet of the text exactly as written so that I could find it easily. There is, after all, only so much a writer can with ‘There are bugs in chapter one’.
But the big test was a public release. The public discovered flaws or instituted crashes in a myriad of unusual ways. Sometimes variables were accidentally reset or had odd interactions. Other times certain test were forgotten which changed options, and so at certain points departed characters briefly returned.
Likewise, there is only so much reading you can do before you have to start writing. Your writing will then inform you where you need to do more research.
