Oh God. Back in the relationship game for you, eh?
I anticipate the upcoming review in which you, once again, claim women are evil.
Also, "I stopped caring" sums up my experience with Demon's Souls as well. I had no investment in it. Or to put it in your terms, the context was just not there. The challenge certainly was there, and I suppose there's gratification in knocking over the big guys, but after the thousandth little guy I knock over, the chore becomes more apparent and it becomes increasingly clear that I'm not controlling a character with thoughts, feelings, and drives, but a series of numbers trying to beat other numbers.
And yet, Binding of Isaac (which someone else brought up) stuck with me. Perhaps it's the brevity, or the style, or maybe I'm actually investing in Isaac due to the setup and his depressive state.
