There's really nothing bad I can say about this game; the graphics, gameplay, music, and everything has been so well done, that there is nothing bad to say.
Quite possibly the greatest space shooter in history is right here where the 90's lie, on the PlayStation Entertainment System. Einhander nowadays is pretty expensive, right around at where today's games cost, but prices are rising fast. This is one game that you HAVE to play before you die; you won't regret it. SquareSoft has outdone themselves when they made this; the soundtrack is so amazing, that it even came with its own soundtrack that was only released in Japan. The game is overall appealing to the eye, challenging, fun, frustratingly difficult, and overall absolutely fun to play! If I were you, I'd find this game right now, and take my words of advice for it.
A wise man once said, "Take caution of those in front of you, but beware of those behind you."
That saying is true, because this game has bullets flying all over the place; it's like the "Silver Surfer" of the PlayStation, and that's not necessarily a bad thing, the graphics make up for it, and thankfully your weapons can take damage for you. When they take a certain amount of damage, they are destroyed, and can no longer be used. Same goes for if your weapons run out of ammunition.
Overall, in my opinion, it's the greatest game I've ever played, and always will be. End of story.
