It had been a while since I last played a Raiden game and Raiden V: Director's Cut was pretty enjoyable after reacquainting myself with the series, my eyesight issues aside.  The fact you can beat the game on any difficulty can seem a tad off putting, but this is actually a good concept for newer players so they can experience the story then increase the difficulty when they start to improve so they can get a better ending.  That combined with the boss challenges give quite a bit of replayability  to the game and being able to take things a stage at a time makes it great to play in short bursts.  Overall a pretty good entry for the series.
