It most be my area since if you're playing over 2 hours for a game at 2000 points you're either running a horde list (Orks, IG, or Nids) or you're new to the game. Otherwise almost all games take between 90 and 110 minutes.
Again my point is why play 1750-1850 if they're really just 1500 with a few extra's? If it's about time you're doing it waaaayyyyy wrong.
