Basically, if a game was a PS4 exclusive, it's worth checking out if it comes to PC. God of War, Uncharted, Spider-man, HZD, Ratchet & Clank, Last of Us, Shadow of the Colossus' remake.
I hope that if Uncharted 4 does well on PC that they'll port the 1-3 collection as well. The first game is a bit rough, the second game is a masterpiece, the third game...well, there's a third game. It exists. The second game, though, is so good that I never expected them to be able to surpass it. But they did! With 4.
Kinda sad that only like...two Xbox One exclusives were worth checking out. Sea of Thieves (and that's only *with friends* that it's worth playing), and of course the Forza Horizon games.
