Disc systems are mostly built like shit especially from the early 2000s but ROM based cart systems if well taken care of will run for a long long time.

Have my OG N64, Dreamcast and GameGear all run perfectly fine. Well my GG has a dead spider in the screen but it still runs.

PlayStation 1,2, Saturns , the first 2 Xbox’s might be a different issue all together.

But to me this is connected to the growing eshitification of the industry
