I’d be very surprised if Modiphius did anything other than 2d20 here, it’s their in-house system and I can’t think of a single RPG they’ve put out since the original A!C that doesn’t use it. It’s not exactly surprising that Games Radar wouldn’t know this, but it’s still funny.
I guess technically the first edition is out of print, so Vaults of Vaarn, an OSR adjacent hack of Knave set in a world that’s basically Dune but weirder.
