Is Uncharted: Nathan Drake Collection have all games included in the disc? - PS4

So I saw that Uncharted: Nathan Drake Collection and Uncharted 4 online which is discounted. I was planning to buy it but knowing I have a slow internet connection and it is not good to be downloading all three games so the question is: is uncharted 1, 2, and 3 are already in the disc(Uncharted:NDC) like you can switch to any of the games like Borderlands The Handsome Collection or only 1 uncharted game is on the disc and the rest should be downloaded through dlc. I hope someone can answer the question. Aside from that; I’d also want to know if the games Uncharted 1, 2, 3, and 4 require internet to play coz I was planning to buy Uncharted: NDC and Uncharted 4.

The Nathan Drake Collection contains the first three Uncharted games within the disk. The only thing that would need to download are any updates and patches.

Playing any of the Uncharted games does not require an internet connection. The Nathan Drake Collection only contains the single-player story and does not support online multi-player. Uncharted 4 does support online multi-player, but it is optional.
