What IGN says of GTA 4:

Grand Theft Auto III was a revolutionary title, one that inspired a whole new generation of 3D action games. Grand Theft Auto IV is just as big a leap forward, though perhaps in subtler ways, and sets a new benchmark for open-world games. Everything in GTA IV works in harmony. The story would be nothing without the city; the city gains realism from the physics engine; the physics complement the improved AI; the AI would make no sense without the new cover system. And on and on. There is no one major weak aspect.

A "10" is not a score we give out very often. In fact, the last time we gave a 10 to a console game was Soul Calibur in 1999. A 10 doesn't mean a game is perfect -- it means a game is pushing boundaries, expanding a genre, and doing many things to a level so far above and beyond its competitors that they overshadows any flaws. Certainly, GTA IV has some issues, the most noticeable being the occasional flaw in the cover system, but there are many more pieces of GTA IV that are better than anything I've seen from a game in the past decade. We don't give 10s often -- just to games that merit the score.

What IGN says of Metal Gear Solid 4:

This would be the game that would merit that score. Metal Gear Solid 4: Guns of the Patriots is a title that exceeds all of the hype that was attached to the title. Regardless of whether you've seen every trailer and screenshot, read every preview and heard every interview, you won't get a full sense of how phenomenal this title is unless you sit down and experience it for yourself. Legends die hard and deserve a heroic story that lives on when they are gone. Metal Gear Solid 4 is such an ending for the legendary warrior Solid Snake. Not only does it sum up the full franchise of Metal Gear, its depth and its complexity, coupled with its technical prowess, make it one of the best games of the year and, indeed, one of the best games ever made. Get some well earned rest, Snake. You've earned it. We salute you.
