Birds of Prey was definitely one for the aircraft fancier. You could pick a mission to suit and get into the cockpit of just about anything going, for either side. Handling was appropriate in pretty much all cases and the 3D engine suitably slick. You could mount attacks on ships, factories, and tank batallions. You could drop supplies from your Hercules, or strafe an area with the A-10's big gun. This was also the first Sim I'd encountered in which you could actually refuel in mid air.
Unfortunately there was a price to pay for having all these planes and the touches like mid-air refuels. And that price was the map. Or the lack of it. No Middle East scenarios, no European scenarios, just the one map, with the good guy side and the bad guy side, and that was it. So although you did have quite a few toys to play with, the sand box wasn't very big or varied. Which is a pity, because otherwise Birds of Prey was a very competent Sim. It just wasn't one I'd recommend to, for example, ThunderHawk fans who were used to evolving storylines and varied terrain types." Still a Top Dog, regardless :)
