My collection and general interest is tilting farther and farther toward PC gaming every day, and that's primarily digital. As nice as it is to go into a store and pick up a physical copy to have and to hold.. digital is just far more convenient and often times it's cheaper to boot. There's also an issue of space.. I don't have much room on my game shelf or my room in general, but I have more than enough room in my PC. Far more than enough, haha.
But, in the cases of console games, it's pretty 50/50. Don't really have a preference either way, but like I said before, space can be an issue so if I had to pick, I'd say digital.
Most Some days I just don't want to put on "real people clothes" (god forbid I get put on anything other than pajamas) and go out somewhere, and in those cases I'll more than likely download it. If I'm already out, or if it's a nice day, or if there's a cute cashier involved in this scenario then I won't mind grabbing a physical copy. =p
