Uncharted 4 didn’t do too well on PC? Where are the PC versions of Uncharted 1-3

Release of 4 could have pushed a bunch of sales on a 1-3 PC collection as well! Release them at the same time, put the 1-3 collection on a discount and charge full price for 4. People will gobble up both. (I would put 4 on my wish list and buy the 1-3 collection in that situation, but that is still me giving them money for a two-decade-old game.)
