Uhm uhm, someone has forgot to mention God of War and Spiderman in his post. Interestingly, these four games sold more than any other game in their franchise.
RDR 2 sold more than RDR in 8 days
AC Odyssey was the fastest selling AC game on current gen
Spiderman was the fastest selling Spiderman game
God of War was the fastest selling God of War game
Didn't forget, merely used the two most recent and most record breaking examples.
I have GoD, but not Spiderman, decided I need to wait since I've bought far too many games over the past two months. Finished AC, about to finish RDR2, and then I need to finish Pathfinder: Kingmaker.
