Here are some things you can do to get "moar" out of the game:
1. Take 25% fuel and drop tanks on every a/c that has drop tanks available.
2. Retain your drop tanks until they're empty regardless of whatever ACM you're attempting.
3. Fire only one bank of guns at a time (in like-caliber configs).
4. Fly a 40 ENY bird for an entire tour (I did the Spit 1).
5. Jeeps, more Jeeps, and Jeeps.
