Hello! And yes, there are!
I know less about table game but Shadows over Camelot seems to be THE board game for arthuriana. Then there is the RPG King Arthur Pendragon (quite famous too) by Greg Stafford (and here he recs some other rpg games).
There are also some videogames, some of them quite old and free. But let’s start from recent ones:
- Fate/Stay night and series (visual novel)
-
Shall we date?: Magic Sword+
(android game) - Princess Arthur (visual novel)
- Lancelot’s hangover
-
The Order: 1886 (arthurian inspired)
- King Arthur the roleplaying wargame
- Excalibur: Morgana’s revenge (sort of inspired)
- The 2004 movie King Arthur videogame
- Sonic and the Black Knights
About older and most of the times free games:
- Conquests of Camelot
- Legend of Galahad
- King Arthur’s World
- Arthur: The Quest for Excalibur
- Camelot Warriors
- Conquests of Camelot: The Search for the GrailExcalibur
- Lancelot
- Spirit of Excalibur
- Vengeance of Excalibur
- King Arthur’s heir
- King Arthur and the Knight of Justice
…. I am sure I forgot some!
