Help me complete this list, but some things that you should not tell me to add are: Games that have no chance of being released outside of Japan at all. Games that are unnamed, rumored, or have no official platform confirmation (If you say Kingdom Hearts 3 Wii Soriku I swear I'll ban you). Now have at it.
