...Yeah right!
Final Fantasy games only allow a certain amount of members of your team to be used at once. It is usually four, but in games like VII, VIII, and X it was three, and in IV it was FIVE for some reason. Because of this the game has to come up with excuses as to why only so many of you are on the main mission (while others are... I dunno, maybe down the pub somewhere?)
The most common seams to be that it is "too dangerous for a group". What? I thought there was "safetey in numbers" or something?
Any particular excuses you liked in the subject?
