Clearly rare but fun.
The entire background is black and the graphics are like what you normally see on this computer, the pink, white, blue and black graphics. It seems bland, but it's addicting. You'll spend awhile shooting down different jets and such. Though it can get repetitive.
The controls are confusing at times, sometimes you gotta use the numberpad or something of the sort. Playing two player can be harder, being you basically have to reach across eachother to hit your own key.
The difficulty is medium, it isn't too easy nor is it too hard. It's mostly just repetition, but each enemy gets harder and harder. Though definatally a classic for jet sims. Yes, this is one of the first to hit the market as far as a jet sim goes, however sadly a least known.
The learning curve I would say max is an hour, being that the controls can be confusing because you have to do this and that, a lot of stuff to avoid missiles also. The weapon selection can be slightly difficult to get used to but it's definatally not as confusing as the modern flight sims.
You're a person of the classics and you have an old computer like this? Get it, it's really good. It's basic definatally, but doesn't change it at all.
