Shitty (nonexistent) marketing.
Sadly it doesn't matter if a game is good, if you don't tell people it's good then nobody's going to buy it. Word of mouth can only get you so far, and not every game can be Demon's Souls in that regard.
In 2008, the week Valkyria Chronicles came out (a sony exclusive) all the marketing was destined to LittleBig Planet and a Motorstorm game. Long story short, nobody knew Valkyria was coming (except jrpg fans obviously).
