Ubisoft blames Sony for 'directionless' PSP
"It's direction, a real strategic decision by Sony as to what it wants to do with that product. It's a great shame that sales are at the level they are, because you've got a hardware system that is absolutely beautiful ... we're not developing too many games on it until we get some direction." Ubisoft currently has zero PSP games in development, a trend not uncommon amongst non-Japanese publishers at the moment.
Ubisoft is responsible for a number of flawed PSP ports, such as Rainbow Six Vegas (Metascore 60) and Ghost Recon: Advanced Warfighter (Metascore 61).
