How can that possibly be true? Top 10 selling 360 and PS3 games:
2 COD4 - shooter
3 MGS4 -shooter
5 R1 -shooter
7 COD 5 - shooter
9 Uncharted - shooter
1 Halo 3 - shooter
2 COD 4 - shooter
3 GTA 4
4 GOW - shooter
5 COD 5 -shooter
6 GOW 2 -shooter
8 Forza 2
So, 5 shooters each? There's no argument there.
Having a gun in gameplay does not qualify a game as a shooter. In this case you should have made GTAIV a shooter but you did not because it is a sand-box game and the game isn't entirely based on just gunplay.
Uncharted is an action/adventure. Metal Gear Solid 4 is a Stealth/Espionage. This is just like how Splinter Cell isn't just a "shooter".
Yes MGS4 can be played like a shooter, but the core focus on gameplay is not, that is why there are trophies for killing no enemies and not tripping any alarms.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
