G-darius (psx) : perfect shoot'm up!!!!
Couldn't agree with you more. It is personally my favorite shmup series (and the best one. I R FANBOI! XD)
Don't forget about the music.
I would do it (by playing Taito Legends 2 for the PS2, which is based on the Arcade version), but I suck HARD at it (it IS Darius, after all.) I can make it to the 3rd zone (after Queen Fossil) without dying, but that is IF I don't die on Queen Fossil. After that, it goes downhill.
