That's it! No more Assassin's Creed Odyssey for me. Finally got all achievements in the game and its DLCs after 95 hours of play time (86 hours according to the in-game tracker).
Deleting the game also gave me 95GB of space for other games. Very happy with that.
I'm currently trying to 100% ACIII Remastered right now. I always end up getting burned out for several months on AC games after I 100% them.
