I'll answer you the same I did with my wife and mother since they told me I should go with the hard copy.
1. I save taxes, which for me was 12$. Not a big deal, I know.
2. It's ecologicaly more responsible to buy digitaly instead of hard copy. It's not a big deal, I know
3. I thought I could start the download, get to bed, hit the gym, came back home and install without having to make a cut towards a store to buy it. Again, not a big deal.
It's the 3 reason. I can also add that I bought a few games on the PS3 and PS4 and downloaded them without problems. Therefore, I wasn't expecting a problem with MLB 14 The Show.
What I should have done is read more about Day 1 Digital delays before pre-ordering. That's my fault on that part. Next time, I'll know better.
