jgwhiteus said:What other games were in FF Collection? (did it include VI and/or Chrono Trigger? Forgot what games were in that in the US). Because you could add 400K to those games as well - it's hard to say which games were "responsible" for FF Collection's sales though, or if it was just the fact that it was a collection.
I actually didn't realize FFIV had been released as a standalone on PS1 in Japan at all.
The standalone releases for FFV and FFVI sold far lower than FFIV's. FFVI's was actually released the same day as FFC if I remember correctly, and sales were very low as a result. Still, that's a lot of FFIV PSone.
