However, the PSP version also has a bug relating to in-game companions that is not present in the DS version; the companions' stated special abilities do not work. While game designer Steve Fawkner has acknowledged this bug, he claims that only Vicious Cycle, the port developer, has the ability to produce a patch. The PSN and European version of the game do not have the bug. In addition to releases for the PlayStation 2 and Wii consoles, the game was ported to Xbox Live Arcade, using the service's built-in networking to allow players to compete online similar to the player matches available in the DS and PSP versions. An updated version of "Puzzle Quest", adding in an additional quest line "Attack of the Golem Lord" atop the existing content. The title, named "Puzzle Quest: The Legend Returns", was released on 19 September 2019. An expansion for the game, Revenge of the Plague Lord, was released on 23 July, 2008 for the Xbox Live Arcade and was included in the 9 October 2008 release on the PlayStation Network. It was also released as a free update for the iPhone OS version. The expansion features 4 new character classes (Bard, Rogue, Ranger and Warlock), and an expansive new area on the Southern Map containing more than 25 challenging quests, 50 new spells, 40 new magical items and new monsters to combat, as part of the story of Antharg, the Lord of Plague and brother to Lord Bane. "Puzzle Quest" was a giant surprise hit, receiving very positive reviews from the gaming community. IGN stated that the PSP version of the game, "managed to combine the best aspects of both [puzzle and RPG] genres into one nice little package." "Hyper"'s Maurice Branscombe commends the game for being a "fantastic puzzle game, mixed with simple, yet compelling, RPG elements". However, he criticizes it for having a "cookie cutter RPG story". MTV Networks' GameTrailers awarded "Puzzle Quest" the title of "Best Puzzle/Parlor Game" of 2007. Future's Next Generation online ranked it as the 17th best game released in 2007. GameSpy awarded it "Best Xbox Live Arcade Game" of 2007. The Xbox Live Arcade version was listed as the 6th best title of all time for that platform by the IGN staff in a September 2010 compilation.
