What Game(s) Should I Buy With $20?

That’s strange, I thought Sony claimed that the PS4’s controller would have native Windows support.

I would suggest Stalker Shadow of chernobyl! but out of your list. maybe Deus EX, Don’t Starve, NOT Legend of Korra (it’s not that great of a game.), The Forrest, FEAR. You can ger all the Stalker games I think for under 20$? Or at least 2 of them.
