Video games are a horrible comparison of what zombies "would be like'
As in "RE zombies or L4D zombies" all in all it's just another work of fiction based on common beliefs of zombies portrayed in their own way for entertainment purposes.
everything is horrible in comparison to what "zombies" would be like.
The only thesable viral zombification is one that kills everything in the brain except the basics by that I mean only things that let your live so the frontal lobe and other places that make you, you would be dead. If you wanted that said "zombie" to consume human flesh you'd have to somehow imprint an instinct in which that is a viable food source.
