New games that have low ratings will probably be influenced by you. Also, who the hell wouldn't give the Last Stand a 10? It just shows how incorrect the ratings are.
I rate on fun, controls, and story. Some games have bad controls and story, so they get a 4 since fun is in the game. I rate on other things but those are the 3 main things most games have(I mean story,not all have one). But yes, most new games are rated bad maybe because not origional or made quickly so I can't explain it more than all of us at armor games.
