Yeah, an odd choice for sure. Seems like the main reason it is on their list is simply because of the temporal injection technique they use to make it look closer to native 4K on PS4 Pro.
Not odd at all. Spider-Man handled things that God of War couldn't (given the nature of the game). Although God of War is more impressive visually, Spider-Man handled things in ways that few open world games could have ever dreamed of.
I think it's just because the list is best tech this year rather than best graphics that is throwing alot of people like myself off. Graphically, God of War looks quite a bit better than Spider-Man, higher quality character models, better textures, etc. But since it is best tech this year, Spider-Man wins out due to things like temporal injection and the open world tech.
Otherwise, I agree with Battlefield V and RDR2 for sure, both look great. Hunt, Shadow of the Tomb Raider, and Forza Horizon 4 are real lookers as well. A few of their nominations though like Onrush, SotC remake, and Kingdom Come I'm not all that impressed by graphically personally.
