The numeral in the title has been used very inconsistently on Kickstarter. The big colorful logo uses the Roman numeral, while the entire description text uses the Arabic one. Which one is official or, at least, more official than the other?
I am asking mainly because I am maintaining several wiki articles and they can only use one or the other title spelling in their own titles, not both. Wikipedia, for instance, currently uses the Arabic numeral, while TV Tropes goes for the Roman one.
