Why Little Big Planet had low sales...interesting read

Why I think it did not sell well:

1) Bad advertising: You dont even really know what its about from the ads sony has done, and most people will be turned off.

2) Its not a shooter: This gen has mainly all been about shooters and playing online, well LBP is not a shooter, so gears 2, farcry 2 and most other shooters will beat it just for being a shooter...

3) betas: I only played it for a week but I made a few levels, and some people managed to completely master level making (lbp calculator for example) so whats the point???
