The title should make it clear, but the purpose of this poll is to record the Flood's favorite Halo game. Except that you can't pick the Halo that you played first. Since people would naturally have a bias for that game you can't pick it. So if the first Halo you played is your favorite, pick your second favorite. If you played your favorite Halo after your first, then you're fine, just put your favorite. I'm interested in seeing the results.
