If you are counting it like that then guess we better count all the psp as seperate and the vita one aswell? Then we also better get rid of Tools of destruction cause its techically more than 6 years old having first released in October 2007. This is just stupid,  except your wrong. you can't go counting old ports who the heck does that lol Maybe I should have wrote it in a more basic way so you would have understood it easier, If you look at the other titles I used as an example e.i Killzone or Assassins creed you will find that I did not include collections or hd remakes even though they both have them, but including them is just pathetic lol 

The end, unless you have another franchise.
