The Big M is hiring for development on something that will surely please fans of the strategy genre.
Over on Microsoft's careers site, there's a job listing for a Senior Software Engineer who's interested in joining a brand-new development team to work on a new entry in a "beloved strategy game franchise."
The Decisive Games team is focused on world class strategy game development, and is building a studio that will bring the next installment in a beloved strategy game franchise to the next generation of gamers around the world. This is a highly-collaborative, agile team, with a play-centric approach to game development.
The company's biggest strategy franchise is undoubtedly Age of Empires, so there's reason to believe we'll be getting another one of those. However, Microsoft has been pushing Halo hardcore these days, so a new Halo Wars wouldn't surprise me either.
