That does it! From now on...

[cloud21zidane16]

i usually go with roman numerals but if im typing quickly i use arabic.

[Breine]

I prefer the Roman way of doing it.. It looks cooler

[Momiji]

I'm always going to use Roman numerals, Arabic is for n00bs.

Seconded.

[Mercen-X]

Roman is for full-writes: Final Fantasy I, II, etc.
Arabic is for shorthand: FF3, FF4, etc.

[JackNapier]

It all depends on my laziness.

[Takara]

Roman, most of the time. If I use Arabic, it's either because I'm really tired or writing to someone I know doesn't have a clue about Roman numerals.

Regular numbers are fine...if you're a simpleton.

[Sefie1999AD]

I used to use the Roman numerals for full-writes (Final Fantasy VII, for example) and the Arabic numerals for shorthand (FF7, for example), but nowadays I just use the Roman numerals. FFX was shorter to type than FF10, and FFX-2 looks a lot better than FF10-2, so I decided to use Roman numerals for all the FF games for the sake of consistency.

[Jess]

I use the roman numerals most of the time, but sometimes I will just use numbers instead.

[Miriel]

Roman is for full-writes: Final Fantasy I, II, etc.
Arabic is for shorthand: FF3, FF4, etc.

Pretty much, yeah.

[Yuffie514]

i use Roman numerals to show some respect. but i can use Arabic if i just wanted to be a little lazy.

The last one you've got in your little poll there sure is funny 'n all, except since you're stating it as a title, it's also the proper way to do it.
