Wow! If we are that lucky every scenario, my group should do well.
Four investigators, zero monster surges. On four different occasions, a gate appeared on a location where an investigator had just closed the gate. One Elder sign used. One gate that opened during a location encounter (no doom token for those) Doom track was at 8 when we closed the 8th gate. By far the shortest 4 player arkham game we have ever done.
