Hmm...
I just got Ghost Pilots a little while ago, and here's my take on it:
Gfx is nothing great. Expect 1991 graphics.
Music is boring but there are a couple good tracks. The game and controls are very simple. A= shoot, B= bomb. If the game were updated today, it would at least use 4 buttons and have charge shot.
But the action onscreen can be furious at times, and as a shooter fanatic, it does give me a run for my money. And many of the bosses are good to. Good practical scaling effects of bosses moving in and out of the clouds, stuff like that.
