Yeah, doing a save before 20th scene would probably be the best as that's where routelocks and relationships with girls tends to start. I think the earliest routelock starts on scene 020, but some do come a bit later depending on a character
Appreciate the quick response, ended up locking myself into Aida's route first time around, reset to see as much as I could. Still planning on making her my first playthrough (mainly due to her tying in first place so far as personality and likability with Naomi for me), but I'm getting a lot more skill points and events after resetting and trying with the others, so all's well that ends well I suppose. Guess I'll grind each of their routes to 20 and make a save there.
