Actually, you should have said that Santa Monica took 13 years between God of War 1 and God of War 2018, and that's why they are a terribly managed studio
In your eagerness to defend XGS and blame PlayStation Studios, you forgot that Santa Monica also released God of War Ascension in 2013 and then co-developed and released The Order 1886 in 2015, and then released a game-of-the-generation God of War in 2018 (despite having a canceled game in between) and also already released God of War Ragnarok in 2022.
My sincere advice: instead of going into this 'whataboutism,' you should instead question XGS and why it's taking so long for them to fulfill their promises. Because "lack of games" is literally not a problem or concern for PlayStation gamers at all. They are very happy because they continue to get 4-6 high-quality exclusive games every year (which is already more than what
MS hopes to achieve in the future). Critically questioning the companies you like help them get better. If more Xbox fans do that, Xbox will deliver better products to everyone.
Also, this thread is about Xbox games, not PlayStation. You're forcefully involving PlayStation Studios in this discussion, which will inevitably lead to console warring. Avoid that.
