Sony is sending word that it will add quite a few interesting games to its PlayStation 3 Greatest Hits collection. That means that the games will be re-released with a new and shiny packaging and for the rather low price of 29.99 dollars, which is half of what a videogame tends to cost on launch. All the games introduced in the Greatest Hits lineup will be on sale on June 16.

The six titles that are being talked about by Sony are: Army of Two and Battlefield: Bad Company from Electronic Arts, Devil May Cry 4 from Capcom, Gran Turismo 5 Prologue from Sony , Metal Gear Solid 4 from Konami and Ratchet, and Clank Future: Tools of Destruction from Sony.

The big news here is, of course, the launch of Metal Gear Solid 4: Guns of the Patriots, which came out last year to tell the end story in the saga of Solid Snake. The release offered a lot of cutscenes, many extraordinary moments and proved that Hideo Kojima can still create videogames able to change the way gamers look at the industry.

By adding more titles to the Greatest Hits line of videogames, Sony is hoping to attract more buyers to the PlayStation 3 gaming console, which has seen less than stellar sales in the first months of 2009.

Sony is probably betting that, with games that are attractive and sport high production values being offered for half the price they cost when initially launched, more gamers will be willing to pay the price of the console, which is higher than that of its rivals, the Xbox 360 from Microsoft and the Nintendo Wii. If the Greatest Hits move fails, then Sony might come under more pressure regarding a price cut for its gaming device.
