It was so good I though my Amiga were arcade-machine quality.
Much games were pale in comparison to Battle Squadron. ( Sonic Boom, Scramble Spirits, GeminiWing,.. )
Frankly, at the time I wouldn't havent criticized if you would saturated the market with similar games. Because with that quality it would have been a landmark for Amiga.
Or that you would have tried with an horizontal scroll.
