It's nothing to be upset about since you don't have to buy it. Why are people acting like Naughty Dog is extorting them?
Some fans will buy it again but this remaster collection is really great for and geared toward brehs that only rocked a 360 last gen and got a PS4 this time around. If you already played the games just ignore it, no skin off your back.
Why waste time doing that when new games can be in production instead?
