So normally I don't comment on other games on the SP forums, since it's mostly irrelevant. But... Sometimes you gotta make exceptions. So I was playing Gunship III (a Vietnam War flight sim) and flying in an F4 Phantom, about 50,000ft above the enemy base, afterburners on, reporting enemy movements. Then I notice the fuel: 20%. And it was dropping. RAPIDLY (Thanks afterburners). Distance from home? About 55 miles. A few tense minutes of careful fuel management later, I landed at the base. With less than 1% fuel left. Phew!
