Properly a low percentage completed all routes and all scenes.
- Just to complete all the Free-Roam scenes you need either to play the game a lot or use the guide to get all of them.
Many free-roam scenes are not that easy to unlock.
- To complete all scenes for all routes, you need to save the right places and go back and replay some content and to switch to all routes, its a massive undertaking to do. And require a lot of dedication and time.
- Many people play 1,2 or perhaps 3 routes, and then they go to the gallery and see what they have missed.
Which is kind of the 'down side' to working/building an RPG around a route concept. Restarting from the beginning each time tends to be tedious in an RPG.
For RPG's I tend to prefer the 'main path' with 'branching subquest' approach where those subquests lead to more scene/CG.
Basically, I generally try to get as much CG as possible in 1 single run and tend to just use the 'unlock switch' once I finish the RPG once. With CG's/scenes unlocking 'organically' being my preference (e.g. not having to perform any manner of hidden tasks you'd be hard pressed to find w/o a guide and them just happening while either going through the story or obvious subquests).
As such, I never really end up doing virgin runs or anything like that (as that would lead me to get close to 0 scenes/CG.
Also ... I kind of find it even harder if I need to purposefully lose (multiple times) to get into the various routes (e.g. the OneOne1 approach). Even after doing these types of games for many years, it still goes against my gamer nature.
A VN generally does the route thing, but well ... it generally feels like less of a chore to start over & hold CTRL until the choices popup and you can do route influencing stuff (or SKIP just auto-stops as you've entered unread territory).
