I submitted a game request for Metomaqester, but in Japan it is known as Oni - The NInja Master.  How does the site deal with this?  Will it be searchable under both names?  Would I have to set that up somehow?  Thanks.

at this point, you'll have to choose one or the other.
multiple names for one game isn't possible atm.

Use to be a space for Japanese names of a given game, but people didn't put in the right characters, so it was taken away.
