in koikatsu there's not as much freedom of interaction as in aa2, you can't fight other characters or force them to fight each other, you can't get your teacher fired for fucking his\her students, there's no need to guess your status of relationship with other characters - it's always positive as long as you talk with them. You can't have male classmates as competition, girls don't compete for you too. Because of that it's just like a rip off from AA2. Don't entirely understand why this game exists in the shape and form that it does. However, it wasn't supposed to be an AA3. I think that it was supposed to be entirely a VN with interactive H scenes, but somewhere along the way they decided to experiment and add open world sandbox into it, cutting the story into separate optional questlines, all of which, by the way, i consider pretty badly written. Also i fucking hate how everytime in H scenes when you switch position or whatever the girl has to spend 10 seconds saying useless stuff and just halting the process. Is it due to long background loading times, to mask them? Or is it another stupid idea from designers? Who knows, but it's been plaguing all recent illusion releases.
