IMO, it's not worth $250... but if you really like simplistic B/W games, maybe it is to you. There just really aren't many B/W raster games worth that much, and there are much cooler ones out there that you could get for <$250.
It's a decent game, but there's not a whole lot to it. Basically, it's kinda like a really simple Missile Command, except 2 players, and nothing to kill you... you just shoot at planes flying over, trying to beat the other person to it. There are three buttons to control the angle of your shot.
