My problem with GameCube is finding consoles that have controllers with them or finding controllers seperate even. I just never see them in the wild. I've bought a total of two over the years, they were a pair of Mad Katz wireless ones (without the adaptors, of course) for 50 cents each. Granted, there are quite a few PSOnes and 2s and OG XBoxes sold without controllers, but it's so easy to find the spare controllers for them.It's been my experience that GameCubes are stupid cheap. I've got two already, including a second I bought with a handful of assorted gaming items for $3.50. I found a third black Cube at another sale for five dollars; I passed on it because I just didn't need another one. I think the original Wii had destroyed the value of the GameCube system... nobody wants one because the Wii can play its games and do so much more.
Now GameCube GAMES, on the other hand, that's a different story.
The Gamecube somehow how managed to top the N64 in that department as I rarely see N64 controllers in the wild either. My theory is that a time traveler is buying all of them in my area and using them to fight the robot uprising of 2018.
