I would any game with a poor beta would get the curious to exhaust their interest and I felt both LittleBigPlanet Karting and Playstation All-Stars had poor beta's.
LittleBigPlanet Karting has long loading and the focus of fun isn't on local multiplayer (where kart racers do best).
Playstation All-Stars talked about too much, over saturated coverage... causes people to lose interest and most of the gameplay videos shown look like chaotic mess with the four players. Aside from the Robot Chicken video, the game's trailers have also not sold the fun and entertainment aspect of it.
I have PS All-Stars and I think it is a fine and fun game... great for local multiplayer and the game design, mechanics, character diversity, etc all work well for it while controls are generally pretty accessible. I think it will do well in long term with hopefully evergreen sales after some hands on parties take place and word of mouth helps game do better.
