You may be amused to know (if you don’t already) that there was once a Japanese video game company called Sacnoth (https://en.wikipedia.org/wiki/Sacnoth), named in honour of just what it sounds like, which produced, among various other titles, a game called “Koudelka” which featured a young Edward Plunkett (the game was set in 1898 in Aberystwyth) as one of its three primary protagonists. Also featured were Roger Bacon, Madame Blavatsky, and the magic cauldron from the Mabinogion. A very unusual little piece of work, to say the least. Not to say that it was very good, or that it has aged well, but it’s worth looking up on YouTube, at least.
I had known there was such a company, but not that they had released a videogame in which Dunsany himself was a character; thanks for sharing.
Of the games known to me, the one in which Dunsany most prominently features was MYTHOS, Chaosium's ccg of the Cthulhu Mythos. Even there he's a minor character, one of the author allies that characters can bring into the game via the Europe expansion.
And speaking of Lovecraft-as-a-character, just today I found there's another novel out in which he features as a character: THE BROKEN HOURS by Jacqueline Baker. More on this one later, perhaps.
