I'll provide the voice of dissent here and give a rousing "Hell yeah!"
Radiant harkens back to the days of the MegaDrive and PC Engine, in terms of being a shooter modeled for the consoles. Yes, I know there was an ST-V arcade version, but when you play the Saturn rev it's very clearly more of what the developer intended. I love the six different weapons and the Radiant Sword is easily one of the coolest weapons in a game of this type ever. Throw in the excellent Saturn exclusive anime cinemas, the incredible score, and a plethora of unlockables and potential score challenges, and I think the game actually deserves the price it begs.
Do any of you really think it has a graphical equal on the Saturn? I still think it does some very impressive tricks, with all the line scrolls, transparencies, etc. I think only Soukyou comes close personally.
Ikaruga is also a great shooter, but much more of a modern minimalist thing with the jillions of bullets/vertical gameplay.
