Why 'Other' or 'Misc.' is not a good idea:No 'other' or 'misc' was provided because the categories should cover all possible cases. It's a general category after-all. The specifics go in the additional field. Let me tell you why this is important. Ultimately, we may have a way to search or list say all translators, all hackers, all script editors, graphic artists etc. in our community, all in organized lists. This will only work if it remains tightly organized. If you have something that potentially can't be categorized in the existing categories, we can add something appropriate.
Lashiec:KingMike got it right. You'd use the 'Original XXXX' options to credit inherited work. If multiple groups released something, you could specify which group each person belongs to in the free text field if you'd like, but it wouldn't be required.
If a project was released by and done entirely by one person, I suppose it would not be absolutely necessary to credit, however by crediting it would be clearly indicated that the project was indeed a one person project. I'd probably lean to saying yes, the person should be added to the credits.
Multiple Tasks by Single Person:I've been thinking about this and reading the comments here. I have a few points to make. First, it is actually typical to see names listed multiple times for different jobs in credits of any media (movies or game credits for example). Second, while feeding my inferiority complex to Moby Games,
look at this. Notice Ben Geisler for both programming and production. I think the issue here is because our projects are done by so few people, it just looks wasteful or out of place to list people multiple times.
So, if someone both translated and hacked a game, why NOT have them listed twice? Now, I do think there should be some guidelines. Theoretically, I could list myself for my projects for Hacking, Graphics, minor translations, music, and script editing. However, that would be ridiculous to list myself for 5 or 6 jobs regardless of how it were implemented. A general rule should probably be following Kaioshin's advice and choose the most important category and list minor specifics in the free text. However, if you really did two major jobs and really think you should be listed twice, then perhaps that should be allowed.
Maron/DS:I don't think we can do what you describe with what we have. You can't append notes to the category, unless I misunderstand. Initially I thought of ditching the categories entirely and just having the free text field. However, by having the category organization, we can potentially do some cool things in the future such as those mentioned in the top of this post.
