"At the time the original comics came out, Mayfair games did a role-playing game that Alan helped write bits of, and it's completely canon, so this game uses a lot of that less-well known material," said Gibbons to Eurogamer.
Mayfair Games produced two RPG modules based on Watchmen in 1987, titled "Who Watches the Watchmen?" and "Taking out the Trash."
Developed by Deadline Games, Watchmen: The End is Nigh (PS3, 360, PC) is a downloadable game that will mix beat-em-up combat with investigation puzzles. While Gibbons admitted to not being familiar with the finer details of the game, he did provide some information.
"Basically, it deals with Rorschach and Night Owl in the days before everything went wrong, and it features a few other characters and villains that are hinted at in the graphic novel," said Gibbons. "It's written by Len Wein who was the original editor of the graphic novel, so it keeps it all in the family, which is nice. And I've been consulting on the cut-scenes which we've tried to retain the atmosphere and flavour of the artwork."
Though the game may be "canon," Watchmen writer Alan Moore has sworn off involvement in any film or videogame productions based on his work.
When asked whether Moore was curious about any of the Watchmen-related projects, Gibbons responded: "No. Strange isn't it? ...As Hollywood is all about credits and money, he finds it rather amusing. He tells me that he likes picturing the studio executives' faces when they find out he doesn't want any cash--he says you can't buy entertainment like that."
Interesting. I've wanted to play the Mayfair games but I haven't been able to find them. I guess this will have to do. Hope it doesn't suck.
