How the heck is that "my opinion"? Do 20 games exist that can only be played on the PS3? Yes. That is factual. Therefore, a top 10 games NOT ON 360 lists is factual too. It doesn't matter how you, I, or anyone else rates those games. If they exist, they can be grouped into a numbered list which we will call "Top Ten PS3 Games Not on 360." What's so hard about that to understand?
Not hard to understand if you want to make literal lists. I however have standards and would never consider the garbage currently available to be included or worthy to be on any list other than maybe a what not to play list.
