Three. While it lacked several "WOW" moments from its predecessors (Like driving that Light car across the city, chased by the Krill, or riding a Brumak in the second game), the story was very great (Gears aren't well-known for their story, but I thought that the third one had a pretty solid one), the multiplayer still maintained its quality (And even when it wasn't nerfed, I never found the shawed-off to be that overpowered! However, the Retro was pretty dirty, and it is still to this day). On top of that, Horde mode was better than never, and the new Beast mode was likeable (not as good as Horde or Overrun, though) and there were lots of things to do and lots of unlockables that kept replayability high. (I still have not unlocked the damned Prescott, but his requisite is way too high T_T).
I think Gears of War 3 is one of the greatest games of the seventh generation. Just my opinion.
