You don't really need the GC controllers for SSBB, you can play very well with just the mote and the chuck, or just the mote. You don't need the steering wheels, you can play MK without it anyway. Balance Board is just for select games.
That would be like saying that you NEED the PSEye, or the Dual Shock 3, or the wireless KB, or an arcade stick, or a steering wheel.
