Eh, honestly, I'm not in favor of that kind of rhetoric. We all waste money on stupid shit I'm sure. If people are entertained, I think they should spend their money on whatever will give them entertainment. I'm in the camp that thinks it's absurd that they're releasing this at $40, but if people have to get their Metal Gear Solid fix, I can understand it. After all, I may not be buying $40 demos, but when I examine my backlog and what I paid to acquire it, I'm not in a position to cast stones at people for throwing money away on this stupid hobby.
Having said that, I would still encourage people to be a tad more critical though. If nothing else, it'd be nice if people did give a little more consideration about what they're paying for instead of just opening their wallets and paying whatever Konami asks because Metal Gear is on the box.
