File size Is not a big issue once u factor in external hard drive options. Luckily for PS4 owners they can switch out the drive. I'll probably end up getting a 3.0TB or bigger external HD down the road once prices drop even further.
You have to factor in streaming in terms of playing while the game is downloading. Unless the campaign is 3 hours long you should be ok. Internet speeds is starting to get better where I live, 150mbs a sec so I'm not worried about how long things take. You can always delete the game once your done with it.
It just depends on re-sale/trade in value. I rather have mostly digital incase my house gets broken into/items stolen/burned down/hurricane/tornado and be able to play them again after re-download.
It's just that simple.
