Games are sorta like dreams. They can be really pleasant, enjoyable and you want to stay in them forever. But eventually you will wake up, either naturally or rudely awaken by a loud noise. And it's all gone.
Video game data is an extremely volatile and fragile, prone to corruption.There's just no telling when it might all be wiped out of existence.
You do better if you accept this to be part of the gaming life. If it hasn't happened to you yet, it will someday.
Yes, it's disheartening to lose hours of game-play but well, shit happens. Put the affected games away for a few months. Play something new. Losing game data is nothing worth getting too upset over.
