Honestly I haven't tried Armoured Core or others prior, the Souls series was my first introduction to them.
Couldn't agree more about Tears of the Kingdom however I'd go one step further and say I can't stand Zelda. I've played a fair few including BotW. Thought they were complete garbage.
The other for me is any game made by FromSoftware, and to that any "soulslike". The game design and gameplay of these types of games are atrocious imo. It has always bewildered me how much love they get. I can't comprehend it.
My wife has these both on subscription as her main brew. I'll admit the biscuit one is nice every now and then. I'll stick with Earl Grey though hah.
I'm seeing this error too.
However the instance I've joined isn't on the list. Not sure what that means for being able to access through the app.
I have a broad taste, but tend to focus on more narrative RPG/Action Adventures.
As for underrated, I loved This is the Police but don't think I've ever really heard it talked about.
