I agree with you, I think Halo will have the best storyline and Peter Jackson is involved, and Bioshock should be good with Gore Verbinski directing, who directed all 3 Pirates of the Caribbean movies, but I think Gears of War will be the best because the director Len Wiseman, who directed Underworld, Underworld Evolution and Die Hard 4, will also direct Gears of War, and he plans on making a trilogy if it is successful. And what do you mean Gears of War is out!, do you mean that it has been released or that you prefer Halo and Bioshock over it, because Gears of War is NOT out, it comes out in 2010.
I think a movie adaption of Gears of War would be more action packed and epic than a Halo or Bioshock movie adaption.
IMAGINE:
the blood and guts, the chainsaw duels, the dilapidated environments and underground scenery, locusts bursting out of emergence holes, the sheer scale and size of some enemies such as Brumaks, Beserkers, Corpsers, seeders, reavers and possibly even the rift worm in a sequel and due to the size of these creatures the battles would no doubt be epic, possible information about the origins of the locusts and their queen, outnumbered gun fights, see the Hammer of Dawn in action on the big screen which will= total destruction, the possible inclusion of General RAAM and possibly Skorge in sequels, pitch black scenes with hundreds of Kyrll hovering above, lots of high powered vehicles, etc.....
Although all 3 movies would be great with a big budget and a good cast and director, I believe that Gears of War will be the best
