Why are you including games from two separate years? 2019 and 2020 aren't the same
Anyways, it's unlikely as far as I'm concerned. The Last of Us + Grand Theft Auto 5 was a brilliant final send off for the PS3 and I doubt any of the PS4's 2020 games will match either of those, let alone both of them combined, so I don't think it will take the title for me.
Because PS5 will likely be out in November next years so PS4’s last 12 months start this November.
TLOU2 + CP2077 look to be great counters for TLOU+GTAV. Then as I said there’s all that other stuff on top of that.
