That's really cool, didn't know you could do that. Just compared mine and 37 games 23% complete. Not so cool. The highest completion in a game is 65% - mass effect 2. One of these days I will go for 100% completion just to know I've done it at least once.
Worst. Feature. Ever. Especially for people like me who have OCD-tendencies. I'm currently sitting at 51% for 71 games. I was just getting over my achievement addiction but now it looks like I got to do some more work!
I just play games for the entertainment factor. Not one for achievements to be honest.
Ah you say that and yet you have one of your games with 100% completion. You just had to do it didn't you ! That's it I too will try for the 100%........just once ! It doesn't help that I have 10 games with 0% complete with one game that didn't load but
still register's......I cant even play it.
