Browsing through the PS Blog, i found a link to an article named "15 games that defined the PlaystationBrand" from Joystick Division. It had most of what you'd expect (MGS, FFVII, Gran Turismo etc.) but then i stumbled upon Ratchet and Clank, which had a video compilation of all the Ratchet Clank commercials for the PS2 and PSP.

These things are absolutely hilarious. I was in hysterics after the "Steve? STEEEEEEEEEVE!!!!!!!" one. I then had a look at the old Crash Bandicoot commercials, which had a guy in a Crash Bandicoot suit standing outside of Nintendo headquarters with a megaphone and a stack of TVs. All great commercials. Why don't we have more of these? I know they're starting to bring it back with the "it only does Everything" commercials for the PS3 slim

but why not the games? All the ads for the new Ratchet and Clank games just use in-game footage.

There are so many games which could have great ads using the old R&C formula. Imagine a God of War commercial. How hilarious would that be?
