1. First. These are games, because the console is needed to play on it. And in this respect, ps4 is just fine. At the moment, there are about 1000 games on it - a list of all games for ps4. And all of them are either high-quality cross-platform or exclusives - that’s what consoles are valued for. PlayStation 4 is the richest exclusive platform. Now there are about 70 of them, including games for the VR helmet. If we discard the games for the helmet, (although I would not say that they should not be taken into account), then there will be about 30 first-class games that every self-respecting gamer must pass - a list of all ps4 exclusives.
And even if you are not interested in exclusives, then playing cross-platform on ps4 is more profitable in terms of money than on a PC, since the system requirements of modern games are not pleasing to the eye, especially considering the cost of at least average gaming hardware.
2. Secondly. Games will still come out. Only for this year, announced a few exclusives and dozens of cross-platform AAA-class. That is, not only is there anything to play in, so the games will still come out. The fact that you do not go through all the worthwhile games before the release of ps5 and even more is guaranteed.
3. Is there an alternative? Let's look at the alternative. PC gaming is not cheap, and I think it's silly to argue about it. Even an average gaming PC will cost several times more than a ps4 slim bundled with some kind of hit. As for the competitor, everything is simple: there is nothing on the xbox one that you couldn’t play in playstion 4. Even the fact that xbox one x is more powerful than ps4 pro doesn't save the situation. In practice, there is no difference in graphics at all. But overpaying $ 100-150 for the console, on which there are no games and which cannot offer any added value, is not at all desirable.
Therefore, do not hesitate - now is the best time to please yourself playstation 4. It remains only to ask which version of ps4 to buy slim or pro.
