quarterly reports of MAU for blizz went from 45mil at OW2 launch to 27mil to 26mil and the last one has 10mil diablo 4 players. It may not be dead but it's hemorrhaging players like there's no tomorrow.
Launch quarter for OW2 also had a wow expansion launch but it sounds like it was mostly bought by the smaller, core fanbase who have kept playing. Either way, adding 10mil MAU in Q2 and not being able to get the number above Q1 via a new game does not speak well of their retention.
It seems to be more or less on life support now. Recycled battlepasses, not a lot of fresh content, slow rollout of promised features. Still, you can have a lot of fun with that game if you've never played it before.
Two Worlds 2 had a very interesting idea for a magic system where you find cards and slot them to create and modify spells. It's pretty jank but maybe worth a look. The game also had one of the most interesting multiplayer setups for open world rpgs I've ever seen.
If you have the steam version of Skyrim it's very simple to get running. https://store.steampowered.com/developer/SureAI/#browse has both versions (depending on if you have the launch version or special/anniversary edition). Also found here is Nehrim, their total conversion mod for Oblivion
