Broken Video Game Consoles/Accessories | Bulbagarden
On my first Nintendo DS, the tip of the stylus chipped off, but it was still working otherwise. The touch screen on the system somehow later seemed to get misaligned when using it, too. Otherwise, the system didn't deteriorate completely, though I did eventually turn it in for store credit, since I have a DSi that still doesn't have either of the aforementioned issues to this day.
My first OG Xbox console died after after some time using it. Likewise, my Xbox 360 got the infamous Red Ring of Death, and after a few simple fixes, I eventually just gave up on it. I did buy used replaces for both consoles, which I still own now.
Beyond that, my family's first Wii stopped reading discs, and we eventually got rid of that. But my parents later bought me a new red Wii for Christmas many years ago now.
