I paid good money for this Dynex!
Glad you got the GC games again. I have the first two on GC, Corruption and the Trilogy on Wii. I like both the GC controls and the Wii ones for different reasons. The GC game controls were built around the controller, and they worked very well. The move/look system on Wii is so simple, but beam switching doesn't feel as fluid as the C-stick. With regard to Metroid Prime still holding up...yes it certainly does. The game will, IMO, continue to hold up really well in the future. It's a timeless classic (just like Super).
For me, the feel of the GC controller is also hugely important. Like, I've never used another controller that's given me this sensation. The feeling when you mash L to lock on to a bunch of enemies in quick succession is distinct. The feel when you press the B-button to jump has a certain amount of resistance to it that wouldn't be the same on anything else. The clickiness of the C-stick as you flick between your weapons. The Gamecube controller has such a distinct tactile response for everything that I just can't imagine using anything else.
I should really buy up like a dozen GC controllers.
