Someone Doesn't Have a Brain
Ok, I'm just gonna state this simply. To make the credits shorter, there has to be less content and less people to work on it. So, we'll have ten people work on the game. Director, Battle Design, Character Design, Story, Modeller, Testing, Graphics Design, Translator, and two more to help at each of those areas. Now, we'll just let all 10 of those people work on Just one Final Fantasy. Estimated time for them to complete a GOOD game, excluding subquests, and other fun side gags (not enough people to do stuff like that) You could have a short version of the game.. in 10 years, on a console that is now outdated...
Credits have a purpose. Your flash file sucked.
