Still waiting on the actual release of MGS5 which I'm sure will include this as a limited edition bonus. I love the MGS series and all but people have to realize that for what it's worth this is a glorified demo.
People claiming that "oh but there is content that lasts for more" have to realize that extra content is not what the average consumer is paying for. It's like saying every 8 hour fps is really a 20 hour game because of collectibles or saying "well yeah that movie was bad but at least the preview trailers were good" *does not compute*
I totally got an extra 20 hours out of cutting every blade of grass in Zelda. So worth it.
