I absolutely adore Shinobi Legions on the Sega Saturn.
The digitized graphics are definitely a bit cheesy (and the live action cut-scenes are absolutely ridiculous), but it all adds to the early/mid-90s nostalgia fun. The gameplay is fun, the controls are responsive, and the boss battles offer some really fun challenges.
I would definitely recommend this gem to anyone who enjoyed the barrage of ninja platformers in the late 80s/early 90s
