I'd be interested in working on some of the more technical areas. I could probably make a good Cid, but there's undoubtedly someone better.
You need to work out certain things like who is going to talk, you need to touch up the script a bit where there's translation errors, decide what "#(@%)" means and if you're going to vocalize those (I think you should personally), and you need to take into account tutorials and areas where you are given instructions. You could make this look better by using Loveless to redesign the instructions, so instead of Barrett vocally saying "Hold [Cancel] to Run." (or something close to that) there's a different style box saying that, omitting that from Barret's voice.
Finally, quality is a MUST. You cannot have adolescent, cracking voices for any of the prominent characters. Severe turn-off, right there.
Anyways, I'd be willing to do some work on the dialog boxes and script if you're interested in doing that.
