"I feel sorry for the people only posting about one manufacturer ( nintendo or sony mostly) because of the amount of amazing games they have never played it really is sad"

That doesn't necessarily mean they haven't played from the other developers.  Like I said initially, choosing only 5 is tough.  I have played others from Sony and MS and love some of them, just not enough to make it on my top 5 :D.
