making games for console games costs lots of money. the development, the packaging, the marketing, the licence fees etc. if you dont sell this game then you really have a problem unless you are a really big publisher with lots of cash in your back.
starfury for example would be fine to play on psp i think but i dont think it would sell in an amount it would make sense to do this. also i think starfury offers too much possibilities for a standard console gamer
