On Reddit someone made a comment that Uncharted 1-3 was available separately on PS4.Well there's your problem, you thought downvotes made sense
I looked on the PSN store, it wasn't true.
So I corrected them. But then I decided to check the UK PSN. They sell them separately. So I corrected myself. Sold separately in Europe, not in the US.
Despite the correction, all my comments got downvoted.
One of my most downvoted reddit comments is from trying to explain to a person that BFR and Falcon Heavy were different rockets.
