Looking great so far SS.
I am agree with this proposal.
What if a game have a different title in the USA & Europe ?
I don't have much examples in mind, but here's come one (currently not in the database, again this is an example)
新創世紀ラグナセンティ is a cute RPG on megadrive
it can be romanized as Shin Souseiki Ragnacenty
US version is Crusader of Centy
EU version is Soleil
i bet US will prime.. but this is debatable..
