I've changed my mind. Halo Reach was without a doubt the pinnacle of Halo map making. Shame on you for not including that perfect game within this list. It is as much a part of the main trilogy as Halo 3 ODST or Halo Wars. The best maps from Reach include: -Pinnacle (Far better than its predecessor) -Paradiso (Best ever big team map) -Countdown (Amazing map, really forced campers to move) But what was the best was Sword Base. Such a great flow to the map. An absolutely flawless stroke of map design. No camping spots, no unfair spawns- it really is the pinnacle of Halo map making. A close runner up was The Cage. That map was exactly what Lockout should have been. Thank you Bungie for such a flawless game.
