Both Xbox Series and PS5 have had an absolutely atrocious launch window in terms of games, I can't ever remember a new generation starting in a more boring and barren way.
Apparently they've just decided that the hardcore fans will buy one even if there are no games, and according to that charts, they will indeed.
Revisionist history and bad use of the word hardcore fan to describe people wanting to get a new console. A launch window is what, six months? By May 2021, there will new games such as Resident Evil 8, Returnal, fan favorites such as Mass Effect Trilogy, and others, if you extend it to 9 months, then you have Ratchet and Clank, FF7 and others as well. The PS4 and Xbox didn't get anything on that level maybe outside TLOU: Remastered which came out July 2014 and Destiny from September that same year.
