Woah! How many times have fans used Sony's third-party team against Sega?
I can still mention other unlocalized Playstation games which makes me mad for SEGA : PS2 SEGA AGES series, Virtual-On Masterpiece, Samurai and Dragons, PHANTASY STAR NOVA!!!
But SEGA fans with Nintenso consoles had it bad too.
All of these perfect port arcade/console games for Nintendo 3DS especially, none of them reached west :
3D Alien Syndrome (port from Arcade)

3D Thunder Force III (port from Mega Drive)

3D Girl's Garden (port from SG-1000)

3D Champion Boxing (port from Arcade)

3D Turbo OutRun (port from Mega Drive)

Plus port from games that makes use of the 3-D Glasses add-on, which are really perfect to be ported to 3DS since they both have 3D function.
Maze Hunter 3D / Maze Walker 3D (port from Master System)

Outrun 3D (port from Master System)

Space Harrier 3D (port from Master System)

All of them, never localized to the west.
Well, Space Harrier 3D was included later in Like a Dragon: Pirate Yakuza in Hawaii.

But unlike 3DS or original version, it lost its 3D effect of course.
