Hey Ki: good to see you getting back into journal writing. I like the OST idea, though I'm nothing like a game head and wouldn't know any of these ones you mention --- think the last one I played was "Doom": yeah, the original!
It's a good idea though, to shift your focus, and hopefully this will give you more pleasure if your other journal wasn't workin' for ya.
Are we to expect crossovers between your journal and your good lady's?
