2 for story and 3 for gameplay.
1 was nostalgic for sure since it was my first game in the series.
Ghost of Sparta was okay and I didnt like Chains of Olympus as much.
Ascension was hot garbage compared to the other games (story was meh, gameplay was okay-ish) but still decent enough, better than the horrible Devil May Cry 2 lol
Scores of all the God of War games I played and beaten - I still have God of War III on PS4 and God of War (2018) to play before I buy Ragnarok.
