I kinda get that. I lot of ntr rpg game I've played nowadays seem to be putting in some effort to making their "good" endings of similar quality to the ntr endings. Like it's not just a shoehorned route, but something that actually feels like a reward for "protecting" the girls.
If Takeda does add a vanilla route, I wonder how much effort he'll wind up putting into it. Will it just be what the demo showed by cutting off all ntr attempts at the beginning, or would he go the elaborate way of making the player work to intercede and mess up the plans of the villains and make people EARN a good ending.
I mean, I'd still go with the corruption route, but depending on how much work is put into a hypothetical vanilla route would determine if a "good" ending is something I ignore entirely or something I'll get a shot AFTER I have fun with the corruption and ntr stuff.
