We use Roman numerals to refer to the American numbered games (II and III, really 4 and 6) and Alphabetical numbers for the Japanese numbered games. (2 and 3 appropriately)

so just a quick note if you don't like the bs titles,
Here's how they are listed on R.U:

1-Final Fantasy
2-Final Fantasy 2
3-Final Fantasy 3
4-Final Fantasy II
5-Final Fantasy V(doesn't matter, there's no other five)
6-Final Fantasy III
