Speaking to MCV, Rockstar Games co-founder Sam Houser has revealed that despite being behind some of the most acclaimed and commercially successful video games ever created he still has plenty left to achieve.

"What have I got left to achieve? Everything," said Houser. "We are only scratching at the surface of games' potential as a creative medium."

Rockstar Games released GTA IV in April 2008 to almost universal acclaim and record-breaking sales figures. The publisher's next title is Midnight Club: LA for Xbox 360 and PS3 and a remixed version for PSP.
