Spider-Man: Miles Morales may well have been expanded DLC but I don't even give a fuck because it plays better than its predecessor both in terms of the new Venom Attacks and because of the animation differences in stuff like Miles' swinging and finishers. The fact that they made the random crimes no longer tied to completion (seriously, five random crimes and then all crime in a district is done was a weird choice) means I'm way more likely to do a random crime on my way to a side mission or collectible or whatever and it feels more organic than just intentionally swinging around one area of the map waiting for the last crime to proc for completion sake. 

While it's not worth getting a PS5 specifically for (I mean it's on PS4 but psssh, 60 frames baby) it's definitely a nice addition to the original game as a sort of psuedo-sequel thing.
