20GB multiplayer download. At least you can play the single player until it finishes updating.
Doesn't affect those without live gold. It's a lot though, I'm skipping 7GB ps+ game downloads as I have to watch my data caps. 20GB is 25% of my monthly limit :/
So was it completed late or are they simply too strapped for cash that they couldn't print a second blu-ray disk. Surely in marketing it sounds better to have 2 disks, than 20GB download required for online play. Throw in an audio CD to complete the package.
