Please help this noob (Joystick question)

So, I’m planning on trying to put together a rather simple arcade stick. I just wanted to find out if I need a 4-way joystick for a xbox 360 controller?

I was wondering if it mattered what stick to buy since there are only 4 directions points on the pad. I hope this isn’t the most retarded idea ever posted… lol

Thanks for the help.

you want 8way.

4way is for pacman and such.
