Roe R. Adams III was the first person in the world to finish the legendarily obtuse Sierra Hi-Res Adventure game Time Zone, which shipped with six double-sided floppy disks and contained 1,500 screens you had to go through to beat it's many puzzles.
There's a Digital Antiquarian article that goes in-depth on how he managed to do it just one week after the game released. It's a great read.
Adams was, as the antiquarian describes him, a prolific adventure-game reviewer and columnist for several magazines. You can find some of his writing in early 80s editions of Computer Gaming World.
To my knowledge, his earliest credit in a video game is in Ultima III: Exodus, for which he wrote the manual and was a play tester. He is also credited as a play tester for Wizardry: Proving Grounds of the Mad Overlord, not the original Apple II release but rather the 1984 PC Booter re-release (which is the version present in The Ultimate Wizardry Archives collection).
Adams was more directly involved in the development of Ultima IV: Quest of the Avatar and according to some accounts it was he who came up with the idea of the Eight Virtues.
He had a minor role in the development of The Bard's Tale, in which he is credited as additional designer. He also designed levels for Championship Lode Runner, the first sequel to the seminal puzzle action game.
Next came his greatest contribution to gaming. Roe R. Adams III was the lead designer in Wizardry IV: The Return of Werdna, working alongside Robert Woodhead to create one of the most insane and wonderful games ever made.
Adams and Woodhead then founded AnimEigo, a company specialized in bringing Japanese animation films to the US market.
He later worked in the localization of two Super Nintendo games (Paladin's Quest and Xardion) and had advisor or consultant roles in a few other titles.
Adams also was heavily involved in the creation of Tokyo Dungeon, a Japan-only RPG released for the PlayStation in 1995 (thanks, newtmonkey ). He is credited as game designer alongside Kazutoshi Ueda, who previously worked on some Megami Tensei games.
After that, any information is scarce. A LinkedIn profile page which may or may not be his would indicate that Adams is or was at some point self-employed and living in Portland.
