Well, I agree with Greg Kasavin with two of his picks: (In no order): Dracula X: Rono of the Blood (Turbografx-16 CD): This game is not even rare at all in Japan, but the game cost over $100 bucks. Why, because there's a huge demand of this game and there's a good reason for it. Totally Un-linear gameplay, one of the best Castlevania music scores, and the first Castlevania game with a lot of easter eggs. If you own a Turbografx-16 with the CD-ROM attachment, or the TurboDuo (or it's Japanese counterpart, the PC Engine Duo), you must own yourself to shell out over $100+ dollars for your copy of Dracula X. Trust me, it's worth it. Ikaruga (Dreamcast): Treasure's genius minds had done it again. Taking a simple shooter and making a puzzle game out of it. A hard game, but very worth it in the end. Now, many people here played the Gamecube version of Ikaruga, well the Gamecube version is not great compair to the Dreamcast version. The Gamecube version might have more extras than the Dreamcast version, but the Gamecube port has some graphic and sound problems that wasn't persent in the Dreamcast or the arcade versions. For that reason many of the hardcore shooter fans perfer the Dreamcast version. If you own a Dreamcast, try to import Ikaruga. Trust me, you'll love it. Gunstar Heroes (Genesis): Treasure's first game and they score big. With the great weapon select gameplay and the wonder enemy designs, Gunstar Heroes is a must if you own a Genesis. The only down side is that the game wasn't popular enough with the general public and people tend to forget this hidden gem. Capcom Vs. SNK 2 (various systems): Fighting fans love the game for it high roster of fighters, and not to metion the groove system. A must for fighting fans. Any Dreamcast shoot 'em ups games that was made after 2001: If you own any of these titles, these games were made after Sega left the hardware market. By owning these games, you're offically cool because you are one hardcore Dreamcast fan: Ikaruga Border Down Under Defeat Chaos Field Zero Gunner 2 (release around the time the Dreamcast was stop supported) Trizeal Psyvariar II I've said enough!
