true to the rules this game fly's...but....If we all agree that fuel is dumb then maybe we could change things. More advanced rules exist, and I believe that Ammo insted of fuel is the way. But then again we can't dive or climb in this game. Rules are rules and not the real world, either we adapt to them or look for other ways to change things. How many times were the original rules for a game great and all the additions and suppliments crap. Take the rules for what they are and learn how to play them.....even if they defy reality.
