Much like Metal Gear Solid 4, Sony is looking for LittleBigPlanet to move consoles from the shelves because all types of gamers are going to want this title. Personally, the desire to want and the stronger feeling of need are two separate problems; everyone will want the game but many will need to buy a PlayStation 3 for MSRP.
Although the prices are slowly dropping for a PS3 unit, hardcore gamers are the ones that will rush out and spend a bundle of money for a console just to play one game. If not hardcore gamers, fans of the franchise (MGS4 for example) and LittleBigPlanet is still working on building a fan base for their new franchise.
The platformer LittleBigPlanet, for many, isn’t worth $399 plus the price of the game. That’s asking a lot, but Sony still thinks it can happen:
It’s going to be a hardware seller. Not only do you have the platforming experience that a lot of other games will have, you have this creativity that really is exclusive to LittleBigPlanet. (kotaku)
Would you run out and get a PS3 for LittleBigPlanet? I’m tempted, but that $399 barrier is truly a large obstacle to clear.
Sony’s been putting a lot of effort (read: money) into the PlayStation 3 product line with very little impact in the market. They’ve got this “10 year plan” but haven’t really executed a strong plan for their first two years of said plan. Sony’s plan seems to be “outlive the competition’s technology” while all of its competition stomps on their sales and market share with older and a bit “outdated” products.
