it's interesting, ps3 has 3 games that sold 5 million, none of them are first party. They have 4 first party games that have sold over 3 million but they have all had a certain amount of bundling. If it wasn't for bundling it would probably only be 2. Sony has been around for quite a while now, they should be able to come up with a few big franchises.
currently playing: Skyward Sword, Mario Sunshine, Xenoblade Chronicles X
