Neither did PS4 at launch. What did Sony actually have before Bloodborne came out in 2015?
Killzone: Shadowfall?
Well, uh, best I can come up with is: before some point, quite a few console games actually were exclusives, but got PC ports over the years. Yakuza 6 was a PS4 exclusive for a good three years
(five in Japan but shut up). I'm sure someone else could name more, I'm drawing a blank right now. I think it's worth mentioning that PC ports weren't as reliably good as they are today, and Steam Input wasn't a thing yet, so a game coming out on both PS4 and PC didn't necessarily mean you'd get a better version on PC like you do today.
Anyway, back in 2013, I don't think anyone really predicted just how lacking in exclusivity consoles would become in the future. It'd make sense not to expect it, since exclusive games sell consoles, and of course they want to sell consoles and get more people in their ecosystem, right? Surely Sony would keep their games they funded and developed on PlayStation, so you have to buy a PlayStation to play them, where you also see advertisements that make them money and access to a store where they get a cut from every game sold, right? Surely they'd never just give all of that to Steam,
riiiiiiiiiiiiight?
Well, it's Clown World, the endless worldwide event where everything's turned on its head, and somehow, PC gets almost everything that's not Nintendo. PlayStation 4 only wound up with Bloodborne and Fist of the North Star: Lost Paradise. When the PS4 was new, there was no possible way I would have predicted that it'd wind up with all of two exclusives worth playing. If I did know, I would have not bought one.
