It had a very hard time against the NDS .
sales wise on its own it did better then PS3 which is good for Sony besides that fact ,
and in japan where it got support.
In the U.S.A it actually had some games in the beginning but soon after just died off ,
besides the few ports it saw of RPGS and Grand theft auto games as well as some of Sony's titles, it was a hit/miss situation
It did get Sony in the door but if the next one falls I dont know what they can do next.
