Tainted Grail: Fall of Avalon is amazing.
I love the atmosphere and music. It also has several quality of life improvements to standard game mechanics. Magic has a Light and Heavy cast which can do different things. For example, a heavy cast might summon a creature while a light cast tells your summons who to attack. When interacting with merchants, you can sell directly from your stash without having to carry it all around.
This game’s biggest flaw is its title.
