If it can be categorized regarding characters, levels, music, plot, mechanics, etc. it would be good.
I would however add (or keep if it's there already) a "Newest Information" section at the top which includes some amount of time most recently released. This way people can regularly check in and come up to speed on the newest data. It would include duplicated data listed in the categories aforementioned.
I think this topic should be kept around and updated up until the game comes out. There will be more and more people learning of the game, or checking in on it after not looking into it for a year since backing, having a comprehensive resource would be very nice for them.
Woaaaah, it finally came out!
