Cliffs of Dover is alright, but I'm more interested in their next product.

Airfield Downtime: Invasion of Moscow

You get to play as a Luftwaffe or Red Airforce Pilot who sits around the hangar looking at snow squalls and your comrads and ground crew shoveling snow and lighting fires under aircraft engines to keep the oil from freezing.

After that . . . Rain Delay: Korean War

Similar to the Moscow addition, but rain and you get to see your fellow pilots (US) stuck on the toilet for hours after trying Kimchee for the first time. North Korean/Chinese pilots are stuck squatting over their dugout toilets with severe cramps after trying captured American SPAM rations for the first time.
