Literally everything in this game is horribly generic. Generic models, generic backgrounds, generic gameplay, standard mind control plot, and worst of all, characters that are the same as not only any other zero-personality waifu template, but also each other in terms of the shitty generic lines they spew.
There are lines literally copy-pasted from one girl to another, and from one situation into another, which is probably the very worst thing you could possibly do in any interactive story-telling medium, like the ultimate form of dismissing characterization as unimportant when it is basically the only thing that is invariably important to any story.
And on top of that the dev wants you to first read his awful info dump of an exposition before the game earns that kind of attention from you, and then go through a tutorial that annoyingly overexplains an already simplistic and self-explanatory UI, before telling you to engage in the most unengaging, zero brain, zero skill and zero emotion kind of grind one could come up with, so you have to earn the right to access his """quality""" content, which by the way is barely there.
I'm giving Sovereign more than 1 star because it is technically playable and the models aren't the worst out there (if not actually good), even though part of me wishes I could just stop trying to be objective about this whole thing and just dunk this game's rating as much as I can with this one review because of what an infuriatingly misguided approach it takes to porn gaming.
Shameful. Just shameful.
