Since Fifa can only be played analog and PES both I wonder what you prefer!
I always play with the D-pad.. I've never even tried analog!

Allthough the first joystick I used to play with is analog.. sort of.

I have always played with the D-pad on my dual analog stick controllers but since this year i'm using the analog stick and i like it now.

Using the analog stick doesn't mean that it is analog.
The game is still limited to 8 directions you can go,
even with the analog stick.
That's why i still use the d-pad.
