My "moment" came after purchasing Batman Arkham Asylum and being hit with a request to create a Games for Windows Live Account. You could skip the GfWL account creation and I did. Soon thereafter was an update. I updated and found all of my save games were lost. Ohh, you didn't create a GfWL account, too bad you didn't create a GfWL... that's the supported configuration.
I stopped following and playing most AAA games at this point, but I was already getting older anyway. I still play video games, but I'm much more careful about the above such things.
