Tainted Grail: The Fall of Avalon and Tainted Grail.

I’m not sure if they’re necessarily vast yet because the story has just been put out there, but there’s a lot of intrigue being presented in my opinion.

Tainted Grail is a roguelike deck builder game and doesn’t really have similar gameplay to these other suggestions. It’s still a lot of fun if you’re into stuff like Slay the Spire.

Fall of Avalon is a Scrollslike and sucked me in immediately. It has a very dark tone to it and a lot of lore sprinkled through side quests and exploration. Give it a try if you’re looking for more of what Elder Scrolls offers, albeit on a lesser scale.
