Many PS4 games are on PS Now which is £8.99/month (though CD Keys were doing a yearly pass for £35, not sure if they still are). Might be worth checking what's on there.
Just gave it a quick check, and think most of the exclusives have been removed.
Mainly planning on getting:
- Horizon
- Ratchet and Clank (Started PS3 version but never finished it)
- God of War (Started PS3 version but never finished it)
- Uncharted(Started PS3 version but never finished it)
- Death Stranding
- Spiderman
- Ghosts of Tsushima
- The Last of Us
- Nioh
I know some of the PS3 versions are available on PSNow, but considering those remakes on the PS4 are <£10 to buy, it's probably a smarter investment to just buy them outright.
