Maybe I should check my local store's GC department. They have almost nothing but what I consider trash titles left, but I bet they're collectively worth about $10,000 right now.
It's kinda like what happened with SNES about 10 years ago, is happening now with GameCube. There's a huge following of collectors on YT going nuts about full-set grabbing on the system. I don't care about the GameCube, but it's kinda sad seeing this happen to any system over time - going from being an accessible thing that anyone can have access to into becoming a hardcore collector's item only. With GC it seems even worse than NES or SNES ever got. Would hate to see the Wii become like this, but it probably will eventually. I'm basically done collecting for the Wii, but still, I'd hate to see it go that way.
