Up to 22 now :)
PSP is my only current platform. I wanted more depth than the gameboy line offered and the screen on the GBA was absoutley horrible. Gave away my trusty GBC and all of its games and got a launch week PSP. played like crazy for 6 months. Then a big lull. TUmbleweeds. Then got the emulators and custom firmware. Then, finally, some new games came out Project 8, FFVII:CC (awesome, 60+ hours on that one!) and now happy with Jeanne D'arc. Hope the trend keeps going....
Trying to convince me the Wii is a real adult game machine 'if you play it right' is like trying to convince me Tofu tastes great 'if you just cook it right'
