This deserves 5 stars just for being the first ever game in existence (as far as my knowledge goes) to have femdom with hyperdimension neptunia. However the plot which often seems to hint to MGQ paradox and all the nice HN girl variations are a very nice bonus on top of that, not to mention that there's some amount of different routes you can take and by a quick glance I took they seem to be very different to each other.
