Aaron Greenberg has claimed that the combination of Xbox 360's exclusive games and franchises coming to the system for the first time - such as Metal Gear Solid - mean that "if you're a gamer, you have to have an Xbox".
Speaking to VG247, the Microsoft product boss said Hideo Kojima's demo of Metal Gear Solid: Rising at the Xbox 360 E3 conference was "the perfect follow-up [to 2009's E3]".
He added: "As we thought about this generation, you've seen that our strategy is to have the most exclusives and the biggest blockbuster games. We've invested in Halo, and Gears of War, and Fable, and Alan Wake, and Crackdown 2, and a lot of the big titles that we think you'll buy an Xbox 360 for.
"At the same time we realise there's a whole set of big franchises that we never had on our platform, things like Final Fantasy; Metal Gear was a great example of that. We feel like we've kind of removed that. Now, all the biggest games are really available now on Xbox 360. If you're a gamer you have to have an Xbox, because that's where those games are at."
