Breja: Logic says DRM-free digital. But screw logic, opening a box and popping a disc into the drive makes me happy.
While the boxes are nice to look at and browse on your shelf, I was always worried about the disc being accidentally damaged or even suffering disc rot over time. Your eggs are definitely all in one basket with a disc.
So even if you screw logic, emotion made me want better than a disc anyway. And disc whirring was also an emotional thing ... hated the noise.
In the end for me, I am emotionally impacted by flexibility. So the logic of whether a disc is better or not compared to a digital download, means the digital download wins out. I can also see to my emotional disc attachment, by burning discs of my digital downloads. It's also not too hard to create your own box or cover for a DVD or Blu-ray case.
Continuing on with the emotional connection, digital downloads can be out of sight and almost out-of-mind, and so reduce depressing home clutter. And that not just being for games, but also books and movies etc.
It also feels great to know I have more than one backup spread around my home, and maybe elsewhere ... less to worry about.
Hell, for nostalgia, I can look at an enlarged box image on my large widescreen computer or TV and drool over that, knowing I have that game safely stored.
Maybe some of that is logic playing a part, but it is also an emotional thing.
But hey, each to their own. :)
