Man, I LOVE that art work for Gradius! I used to to closely examine it many times as a kid. It has that epic Star Wars feel to it.
I always enjoyed the quirkieness of the series. I mean-- where else can you find Easter Island heads that shoot rings at you? Really, the only bad thing I can say about the NES port is that it's inferiority to the arcade version became more apparent to me after playing the arcade original on the Gradius Collection for PSP. I know...it's an unfair comparison. Just say'n.
Great review buddy.
