People are trying awfully hard to prove that games which doesn't feature a cartoon style character are the same, huh? I do admit that makes me chuckle.
It's kind of pitiful, isn't it? This need by a few Nintendo fans to marginalize anything that they don't have? Yeah, we know you don't have a Halo or an Uncharted or a God of War or a Sunset Overdrive but how can anyone think those games are the same? That's silly and you know it.
Look at all the IP Sony released last gen. The Last of Us, Ratchet & Clank, Sly Cooper, Flower, Journey, God of War, The Last Swan, Tokyo Jungle, Little Big Planet, Infamous, Wipeout, MLB: The Show, Fat Princess, Hotshots Golf, and many others. And don't try to tell me, "oh, but they only focused on realistic games, everything else doesn't count." Bullshit. It all counts.
The whole idea that Playstation only targets a narrow demographic is complete rubbish. In fact, the reason I stopped being buying Nintendo consoles is because Sony offered so much more variety.
