The D-pad is used in virtually every game I can think of to switch up weapons, or sub-weapons or magic spells, or whatever. You could replace it with 4 buttons I suppose, but I think it's very easy to parse what's what in your head with that design.|
If they changed it to a GC nipple though, that's be fine by me...
For me, the number one thing I'd like them to do is just make decent fucking analogues. I've lost count of the number of times I've been done in by a difficult to grip analogue, with poor fine control. Give me GC analogues any day!
