I've also read somewhere, though I could never find conclusive information, that Nintendo actually intended for these sticks to have some sort of grease included but was unable to for some reason that wasn't as trivial to explain as "Greedy company wants players to keep buying gamepads"..
I love the "inner beast" which often appears between well-matched players.
Honestly, it's always been one of the ugliest controllers in my opinion, and I was under the impression my opinion wasn't super common. I'm not usually one to care about form over function, but if anything the function is even worse, because no matter how you hold it, 1/3 of the controls are unreachable. If I had a third hand, maybe I'd appreciate it more, but it just looks like it was designed by an alien who had never seen a human before...
A local pawnshop had good copies of Ocarina+Mask; a friend wanted an N64 so I found one with expansion pak (which came bundled with Donkey Kong + Pokemon, which I also sold to friend)... Conkers and Rocket are on my wishlist [they are one hundred$/each].
I'm about to replace all the internal batteries for another few decades of cartridge savestates. So much time. So many memories.
All to say: the N64 Controller is a thing of beauty, and I cannot wait to dual-wield with dual controllers and 8MB RAM. I'm just under forty. Christmas came early.
