PC gamers can now enjoy faithfully emulated versions of PS3 exclusives such as The Last of Us, the God of War series, the Ratchet and Clank series, the Resistance series, the Uncharted series, Shadow of the Colossus, and the Infamous series. Sony recently added Red Dead Redemption, another massively popular console title PC gamers had previously missed out on, to the already impressive 449 other games on the PSNow lineup.
In a way, PSNow is more revolutionary than the PC-like architecture of the PS4. It goes against everything we know about console development and what matters to console makers. Until the advent of PSNow, rights of exclusivity had been consoles' strongest defense against obsolescence. A console is only as strong as its exclusive software, conventional wisdom tells us. And yet here's Sony telling PC gamers, "Look, we know you're not going to get a PS3. That ship has sailed. We also know you really wish you could have played some of our PS3 titles, so we'll make a deal with you: pay us a monthly fee and you can play PS3 games on your PC." In this respect, PSNow is an unexpected software-and-subscription-based iteration of the PS3. It's another option.
That said, if we want to play Uncharted 4: A Thief's End, we'd better be prepared to shell out for a PS4 or PS4 Pro—but will that always be the case? It's an enticing question. When, if ever, will PSNow expand to include PS4 titles? If PSNow continues to get bigger and better (as we believe it will), could there one day be PSNow-exclusive games, like there are Netflix- and Amazon-exclusive shows? All of these questions show that the real power of the PlayStation line has always been, and will continue to be, its software library. It's why we bought our PS4s, it's why we're tempted to buy PS4 Pros, and it's another reason why you'll never see a PS5.
