Sony Santa Monica’s director of technology Christer Ericson says that God of War III will not require any install to run at its best on your Playstation 3.

For many, buying a Playstation 3 comes down to when the perfect game comes along that makes the price point worthwhile. Some bought one for Metal Gear Solid 4 and some are waiting for Final Fantasy XIII, but there are some 800K fans who purchased GOW2 that may be saving their money for March 16th, the release date for God of War III.

Those fans can rest a little easier knowing that they won’t have to worry about any install on their newly purchased PS3s. For money purposes, this means that those who plan to buy a PS3 in anticipation for GOW3 can buy the 20GB Slim and not fork over the extra $100 for a bigger hard drive. God of War III will only require 5mb of space for its save files.

God of War III will be hitting stores on March 16th, 2010 and has been rated M by the ESRB.
