Darius Force (SFC), which left me with a very ambiguous feeling. The whole game feels mediocre, with only a few bright flashes in-between, but those flashes are alone worth playing this game. Like the music and atmosphere of "B" stage, or the creepy snail boss at the end of "C" or the intense action of "M", where you have to dodge falling rocks. There are three ships to choose from, but fewer stages than in the arcade so it seems like every other positive aspect has also its price.
The interesting twists within gameplay mechanics keep this alive, too, I really liked switching between bombs and lasers. Taito's developers made a virtue out of necessity, and put some creative ideas into Darius Force, so the slow SFC can manage the game technically. This also turned the concept in R-Type direction, with just a few enemies around, but well enough placed so to give you a hard time.
Darius Force is a console exclusive and it shows: a low resolution, stiff controls, ship's slowish speed or uninspired enemy formations make the arcade source appear far away. It's still a Darius, though, and if you're fan like me, you'll certainly like it despite its flaws. Too bad Taito never made a Darius Neo
