I guess someone's butthurt because MGS5: Prologue didn't get a lot of hype...
It's really pretty obvious. Infamous is a full fledged game. MGS5 is not. You need 90 - 120 Minutes for the main story. There are demos which entertained me longer. And that's why people call that thing a demo you have to pay for. Because that's what it is. Not saying it is bad or anything, it sure is fun as hell. But still only a demo.
