The best things about the ps5 is the 4k blu ray drive, the ssd, and the controller. I have a flagship 55' samsung and a good soundbar and a highend 4k bluray player is almost the same price as the ps5, so it is really worth it. The 880gb pci 4 ssd ofcourse offloads my PC, I only have 3TB on the pc with two on pci 4 and one on pci 3. The controller is very good and makes a difference, I don't have a wheel so I really enjoyed playing Dirt 2.0 and Ea Sports WRC on it, feel good to drive.
Games otherwise that I played on it are, Death Stranding ( the upgrade version ), ff15, Ace Combat 7 ( but with HOTAS ), Red Squadron, The Ascent ( fun cyberpunk twin stick shooter ), Demoun souls, Jedi fallen order. Planning on playing DS2. In general third person games that don't need mods and require around a 100gb disk space get offloaded to the ps5.
