I dunno man.
I guess it's because I have huge hands that the N64 controller doesn't bother me none.
I don't mind the controller either, part of it being nostalgia as the N64 was my first console, but seriously try playing an N64 game on anything other than that controller. Mapping C buttons to a stick is not a good idea. It's why I gave up on the idea of the Virtual Console back on the Wii, shit wasn't the same.
And before saying anything about the analog stick, it getting loose no longer becomes an issue when you buy a replacement stick off eBay that actually fixes the main flaw with the original. Of course you have to use some tools, but if you don't see the appeal of opening up electronics and modifying/fixing shit yourself, then what's wrong with you?
