Hey!
I love the idea of downloading games but for those of us still with a slow internet connection (most of Australia) the idea is better than the reality at this stage.
For example, I purchased my xbox one as the titanfall bundle about 3 weeks ago, I got home from the store excited to play to discover that the game was a digital copy, no worries I thought and proceeded to download the game. I stated the download at about 5pm on the Friday night and it was ready to play by Sunday morning!!
I actually went out and bought a copy of assassins creed 4 just so I could play on the Saturday, I put the disc in and immediately I was informed that it needed a 2.4GB update, all in all I was able to play my first game at about 5pm on the Saturday night after having owned the xbox one for over 24 hours.
As I mentioned, I love the idea of downloading games whenever I feel like it but for me there are two issues.
1) the massive game sizes and slow download times if like me you are on a slow internet connection.
2) the price of the games is the same, if not more, digital than they are for the physical disc copy.
For now I'm going to be sticking to buying discs.
