So what's your preferred method to getting games.
I can see the logic in getting a physical disk, as the content doesn't full consume the internal storage and you can easily resell.
On the other hand, if you have fast storage, the experience may be a bit better and you don't need to keep a pile of disks around that can get scratched
I prefer digital copy now.
1) It will never damage like the physical copy. If for any reason it's corrupted, I can always download it again (as long as the server still there).
2) I never sell my game collection.
3) I can buy only one copy and play on multiple devices. I often own more than one console (I mean the same console, but different version). So, one digital copy can fit all of them simultaneously.
4) Switch games much quicker and easier. Especially when my wife is sleeping on my lap, or when I am using the remote play function (streaming).
5) Easy to buy, e.g. my wife love to play on day 1. So, I pre-order and pre download for her. It make her able to play the game on the 1st second at the launch day. (I know occasionally can get physical copy even earlier than launch day, but it's not common). It cost my literally less than a minute to buy a game. For physical copies, transportation will cost me at least 30min.
6) Very big discount occasionally (cheaper than physical copies). Most of my games are belongs to the $20 range. e.g. I just bought the Battlefield 1 and Titanfall 2 Ultimate combo on XB store for $26. Both games are enhanced for XB1X, and average $13 each is really attractive.
7) No disc spinning noise, I rally hate it.
And both of my PS4 and XB1 now running with the 2TB SSHD. Which is really great for play digital copies. Reasonable capacity, and relatively fast loading.
