Saints Row may be a little bit late. But I'm sure they can keep up.
In SR3 there was no car scratch effect, but in 4, there is. Also, explosion and its particles are more spectacular in 4, which I totally appreciate. Don't be shittin' me and say there's no improvement in terms of graphic! Lol.
GTAV single player has this wet body effect (when you hit water), sweat (not DOA5 style. It's just a wet patch on your back after walking or running for a while), and dynamic wrinkle normal map which changes the wrinkles on your clothes when you walk and run. These are still missing from Saints Row at the moment. But still, I really appreciate what's there now and didn't expect the quality to be this far back then. So yeah, additional details would be very appreciated. But keeping and staying at the current standard, I still wouldn't be mad.
