PS5 was worth getting for me.

Ghost of Tsushima I played with a PS Plus Extra sub for 30 hours and got sick of it. I would not recommend a PS5 just for Ghost of Tsushima.

Death Stranding I also played for about 30 hours with the sub, and I can recommend playing it and finishing it, although I would not purchase the game to keep.

As for other games, I got the PS5 for GTA V and King of Fighters XV, both of which are excellent. Of the other games I played with the sub, the best were WWE2k22, Final Fantasy VIIR, and Yakuza 0. I also enjoyed Marvel's Guardians of the Galaxy for about 15 hours, although I would not recommend it for purchase. My neice's favorite games were Stray and Maneater.

Games that were not my taste were Returnal, Spider-man Miles Morales, Gravity Rush 2 and God of War: Ragnarok, but a 1 month Plus Extra sub is such a good deal for you to try a ton of games and find the ones you like.
