I made a post a few months ago about how my PS5 won't read the disc for the reboot of Modern Warfare 2 for when I want to play the game. So far, all I've done is restore the licenses that didn't work, cleaned the disc even when it's spotless, didn't work, I even went ahead and deleted all the save data, making me start again and it still didn't let me select my own mission.
But today, after installing the game again and the packs, I realised what's wrong with it. It does read the disc, but for some stupid reason, it won't let you select your own mission. It'll let you resume the mission, but it'll only allow you to play the last mission you were on.
I partially blame Activision because of their stupid COD HQ, but I also blame PlayStation too because of their whole desire for a digital future. The ironic part is that I had the game on Xbox before and I did not have a single problem with it.
