One of my more shameful gaming moments is the fact that I didn't even try to get any decent way through Demon's Souls. I think I got to that giant Tower Knight, killed him, and just decided that I had already went through enough. Then again, I was borrowing a friend's PS3 at the time and needed to play a lot of other games.
Lol, I got to the same point I think. Too much of a time sink imo and not being able to pause/save at any time was a bummer for me who doesn't often have much time to play
