Spartan: Total Warrior from the PS2 & Gamecube was I think an underrated or missed gem.
You don’t exactly play as a lot of mythological things, but it tells a great story with action combat around a lot of really cool mythology. Some of the bosses were incredibly cool.
Elder Scrolls Online, as long as you find a good group of friends.
I also nearly have 1000 hours in MGSV Phantom Pain.
