If Mass Effect 2 is a commercial failure, then what does that make LittleBigPlanet 2? That game has sold only 1.17 million units in 12 weeks, while its predecessor sold 1.82 million units in its first 12 weeks.

That's cause LBP released in holiday season while LBP 2 released in Jan which is the worst month to release a vidoe game in. Sony really messed up with LBP 2 :(

Mass Effect 2 came out in January so what you got to say to that?
