Is Battlefield 4 still playable on the Playstation 4?

I wanted to know whether you can still play Battlefield 4 on the Playstation 4 without any problems or so that it is fun

Why shouldn't that be playable?

Even Bad Company 2 still has enough players to play normally.

The servers are still running and there are still players.

So yes.

Yes, there are still an extremely large number of servers online, at least on the PC
