GC laser died but I don't think it was from too much usage, it died shortly after I took it with me one time to the Middle East and my electric converter wasn't working on it so I just plugged it in directly and it worked for a while lol - had it repaired at a local VG shop and it worked good as new :)

Wii laser died once. I think it was because of too much continuous usage, we'd sometimes play the poor thing almost non-stop for days (taking turns lol) - warranty had expired by then, had to spend 1/2 my new game money on repairs XD

PS1 - started overheating because it was the first generation model. Sent it to Sony and paid 75 dollars because it just went out of warranty. I was pissed about the whole situation since it barely made it past the warranty and I never forgave Sony for it. I am glad because it sent me back to Nintendo.

GCN - I put it in a check-in luggage and on the trip back the hard case suitcase was damaged and the GCN was messed up. Learned my lesson to never put electronics in a check-in bag. I later got it working again but I bought another GCN (which were cheap at the time) to replace it.

lol
