I have 16 PS3 games on blu ray and an additional 3 PSN games.
8 of the 16 PS3 games are first party- Uncharted, Ratchet and Clank, Resistance 1 and 2, Heavenly Sword, Folklore, Motorstorm 1 and Little big Planet.
I assume the PSN games that I have are published by Sony - Super stardust HD, Pixeljunk monsters and Linger in the shadows.
Hope that helps :)
