Itano Circus is a fast paced amalgamation of Freespace, Ace Combat, and Macross. From Freespace I take the general gun layout and the way the guns behave in general. From Ace Combat I take the excellent missile-based gameplay, as well as numerous Ace Combat inspired special effects improvements. And from Macross I get the beautiful ambience of the battle with the ambient explosions, flak, and last but not least, the micro-missile.
Makes the combat fast and brutal with a perfectly balanced gun/missile system. Lack of multiplayer support is an unfortunate flaw.
