With the impact and acclaim that Metal Gear Solid 4: Guns of the Patriots got on its run on the PS3, you'd think that the MGS with Big Boss on the spotlight will also make its run on the PS3 - would've made for eye-popping graphics and great cutscenes again, yeah? Well, certain considerations were made, and it was decided that the War Economy would be better off with Metal Gear Solid: Peace Walker heading for the PSP. Hideo Kojima explains why.

Really, I don't think much about whether a platform's portable or for the home. In other words, it's not important to me. With the PS3, you've got a whole range of middle- and high-school kids who can't play your game because their parents don't let them play video games at home. Those kids can whine at their parents all day about how the game's anti-war and anti-nukes, but they'll just respond 'Well, you're still killing people with guns, aren't you?' and brush it off. I wanted to go the extra mile for gamers in that sort of situation. That was one of the reasons I chose the PSP.

On the same interview with 1UP, Ubisoft creative director Patrice Désilets praised Kojima for his risky move, seeing as the previous MGS installment was on a much more powerful platform.

So at the end of the day, Kojima did it so that more people, particularly the kids, would be able to enjoy the game whenever, wherever.
