I just find it funny that the PSP commercials have never actually focused on a game unless I am forgetting about one . The closest thing so far was the ad with the dust balls that showed about 2 seconds of some of the games. Now, they actually have a game that they feel is worthy of having a commercial based solely on it, and its a freakin' base ball game, like I am going to run out of my house right now, and buy a PSP just for a baseball game that is a clone of any generic base ball game on any other system.
Edit: I forgot about the GTA commercials, oops. That is the only game that I could consider a "system seller." The point about the baseball game still stands.
