I think you underestimate how popular PS is globally.
PS1 sold over 100 million before COD and with Fifa only local play. PS2 had COD and Fifa but they were not a phenomenon till online play really.....
' The best-selling
video game of all-time on
Sony's original
PlayStation console is
Gran Turismo. A
sim racing game developed by
Polyphony Digital,
Gran Turismo was originally released in Japan on December 23, 1997, and went on to sell 10.85 million copies worldwide. The second game in the series, 1999's
Gran Turismo 2, sold 9.37 million units to become the third best-selling PlayStation game of all-time. The second best-selling title on the console is
Final Fantasy VII, which sold just shy of 10 million units.
Tekken 3 is the fourth best-selling PlayStation game, with over 8.3 million units sold, while
Harry Potter and the Philosopher's Stone is fifth.'
'The best-selling game on the PlayStation 2 is
Grand Theft Auto: San Andreas. An
action-adventure game developed by
Rockstar North,
San Andreas was originally released in North America on October 26, 2004, and went on to sell 17.33 million units worldwide. The second-best-selling game on the console is
Gran Turismo 3: A-Spec (2001), which sold just under 14.9 million units. The top five is rounded out by
Gran Turismo 4 (2004) selling 11.76 million units,
Grand Theft Auto: Vice City (2002) with 9.8 million units sold, and
Final Fantasy X (2001) with 8.5 million units sold.'
Also, here is the PS3 list.....

So you can see that PlayStation actually already leans heavily on their exclusives....and always did.
Also when you say the US is the biggest market in the world for gaming.... maybe but Europe is the biggest for Fifa..... 8.6 million units in 2018 on PS4 alone
Released towards the end of 2017, FIFA 18 is part of the hugely successful FIFA franchise of video games.
