After suffering numerous delays, Alpha Protocol was finally released earlier this year to mostly decent reviews. But apparently "mostly decent" just wasn't good enough, as Sega has cited low sales and a low Metacritic average for why they have no plans to make a sequel.
"Let's speak very commercially; the game hasn't sold what we've expected, therefore we won't be doing a sequel," said Sega West president Mike Hayes to CVG. "You know this whole thing with Metacritic where you have to be in the high 70s to mid-80s minimum [to have any success] -- well, with RPGs you have got to be in the late 80s. Whilst we had a good game, I don't think we had a game that had enough to get us to that upper echelon and I think that was the issue."
Although there's no plan for a sequel, Hayes still believes the espionage-RPG concept behind the game -- which was developed by Obsidian Entertainment -- was "brilliant." Still, the economics for a sequel apparently just don't add up: "Again, the amount you need to invest to get there is so large because RPGs are naturally big projects," Hayes said. "We've decided we won't do a sequel."
EDIT : Damn, can you not edit titles? That typo (sequel, obviously) is going to be there forever :D
