i can do that big a change by playing with my tv settings.
You can add particle effects and change costumes by adjusting settings? That's some TV!
And I can't believe I have to explain this, but it's clear that a lot of people don't get it: you can't infer sales numbers of MGS4 based on MGS3, or FFXIII based on FFXII, or GT5 based on GT4. Why? Because there is a world of difference between big games promoted at the start of a console's life, where excitement over new technology and graphics drives hype to a fever pitch, and big games buried towards the end of a console's life, when everyone is already looking forward to the next generation. Of course FFX sold more than FFXII, GT3 more than GT4, and MGS2 more than MGS3 - these games were a major leap beyond their predecessors on the PSX, while the sequels were only a minor jump. We're going to see the same thing this generation, too - FFXIV, MGS5, and GT6 aren't going to see the sales of FFXIII, MGS4, and GT5, unless those games are total crap.
MGS4
is a system seller, and probably a big one. And to know why, you need to look at the hype around it today, not the hype around the game that came before it.
Finally, the trailer?
Yes, it's real-time. Christ. If it's not, then those are some
damn elaborate shenanigans in the videos of the game being manipulated in real time. Would those of you who doubt it happen to be members of the Flat Earth Society?
