To some, these issues might not be issues, and digital download could be the way to go. And lastly, if you live in the US where this 'digital midnight launch' is taking place, you may have an ISP with bandwidth limits, meaning the download is a big bite out of your monthly allowance. Additionally, your PS3 might not have 36 GB of free space if it's an old model or full of other games and DLC. This may also happen if the PSN servers crash with everyone trying to download such a massive file at once with no preload. Second, if you're randomly disconnected from PSN in the dead of night, you'll have to resume things the next day at who knows what percentage level of completion (as my PSN/internet drops out frequently, I can easily see this happening). Therefore, depending on your internet connection speed, the game might not even be done by morning if you were planning on playing as early as possible.
First and foremost, the fact that there's no day-before preload for GTA 5 in the US hamstrings the convenience of this entire process.
