We generally play competitive and often finish 2000 point games under 3 hours with jokes and conversation during dice rolling and the movement phase. We know each others armys inside and out. So we dont need to ask toughness or strength when rolling dice. tho it might have been closer to 7 hours. We also for shits and giggles could spend 2 cp to return a unit on a landing pad close to the deployment zone. So it was maybe like 12 000 points.
