Some people complain that it isn't the best offering as far as recent shooters go but, hell, considering the absolute rarity that is known as the "Decent SHMUP Release", I'll take whatever I can get!
Besides, supporting Chaos Field may at least result in some other titles being brought over here, or at least I can dream of such a thing happening. Well, that and the fact that if Best Buy has Chaos Field in for $29.99, that $10 coupon will...well, let's just say a new shooter for $19.99 would be right up my alley!
