Lets be real part of the reason Xbox 360 had so many sales was because people had a **** ton of xbox 360 games and would have to buy a new one when they invariably went RROD. I know I gave up after my 3rd Xbox 360 ate it. Never again.
You bring up a good point. Though I'd argue that the PS1 (multiple revisions, especially the first one) and the PS2 (multiple revisions, especially the Slim) were the most troublesome, least reliable systems. But yeah since X360 was the lead console for 7th-gen, people have invested in it, and had sizable game libraries. So yeah if they had one die, then they had to replace it if they wanted to keep playing those games.
My brother's original X360 died. Someone gave him another one, which he got soft-modded. Later he also got the final revision of the X360. That one still works fine. Both of his PS3's stopped working, but I forgot why.
My X360 (black Elite which was first X360 with an HDMI port, and I believe it was the Falcon motherboard) actually didn't die from RRoD, it got the E74 error. Microsoft's free extended warranty only covered RRoD. Which meant I had to pay outta pocket to get my X360 repaired.
My PS3 (which was bought as a refurb, and never had a working Ethernet port) had the optical drive die. My friend's launch-day PS3 died from YLoD. But the optical drive was fine. So I took the drive out of his PS3 and put it in mine. Been working fine since.
My PS2 Slim stopped reading discs, and its memory card ports are real sketchy. Thinking about replacing the optical drive with an SD card reader. Don't know what I can do about the memory card ports though. At least my PS2 Slim didn't catch on fire and burn my house down like they've had been known to do back in the second half of the 2000s.
My first PS1's drive motor died. Too bad, that system was hard-modded. Also I think it had memory card port issues as well.
My SNES's CPU died. My Super Famicom has a broken vRAM trace, causing corrupted graphics.
At one point my Wii would only boot to black screen, but it was soft-modded and I had NAND backups and data backups, so my friend (who was the one who soft-modded it) was able to completely repair it, and recover all my data.
My first Sega Saturn (USA model 1) and my first Gamecube both stopped reading discs. But the power going to the lenses just needed to be adjusted by turning a potentiometer screw.
My brother's Mega Drive/Genesis Model 2 has a wonky plug for the AC adapter. You have to press down on the cable where it plugs into the back of the Genesis to make a good connection. We usually just put something kinda heavy on it.
Haha you made me go on a trip down memory lane recalling all the consoles I had issues with (that I can remember at this time at least). I was lucky to avoid X360's RRoD, but yeah E74 got me instead.
Speaking of RRoD:
