I am not criticizing homebrew, I know each creation is one effort. However I notice a stark difference between homebrew games and PSP official. Usually homebres look like Nintendo 8-bit console games. I am not criticizing just wonder what is preventing a homebrew games look like Killzone, God of War or Final Fantasy if we already have access to psp's full hardware? There are a plethora of open source 3D modeling such as Blender. Is not possible to use those?
