The bigger headline says "Microsoft and the Mistwalker" and the subtitle, if you will, is the "Final Fantasy Legend signs on for Xbox 2" part.
Also, a video game cannot sign on for anything. Square Enix would sign on for Xbox 2, if they were dumb and wanted to remake a pretty unpopular game.
Edit: That quote's not from the article, Ashley, I just didn't want to explain the whole thing.
