Halo's not overrated...I dunno though maybe it's just me, but I have not played any other Fps that let's you pull drive by's, use flying vehicles, has such genius A.I, has such gorgeous graphics, has such a good story, etc, etc. I think it has alot of elements that are similar to most fps's but the way it combines them all in one game is what makes it shine. One other wierd thing is that I did not like the game as much as I do until I played it on legendary, and I think above else it was the challenging gameplay that makes me feel it stands alone. I have played dang near every fps and I have never been put through such a rigorous test of speed and skill. But like I said this is all just my opinion........
