While I'm not a huge fan of this card/board game's play mechanics, it has 60 unique cards that depict the main Arthurian figures, plus another 40 cards for famous Le Morte d'Arthur events. I have used the character cards for many purposes, usually showing them to players when they meet the character in question. Also a nice way to draw a random famous joust opponent!

I actually picked this game recently in a trade on BGG just for the very purpose you discussed in your post. Looking at the game last week, I have little interest in playing it as written but as a resource for my GPC game it looks invaluable.
Nice to see that someone else had the same idea :)
