If NG+ came out, the only recommendation with the current information would be to cheat from the start.I'm still guessing this is gonna have NG+ by the end. With the way scenes are built, and the differences with multiple skills, I'm betting you'll be able to reboot at max stats.
There's no incentive not to cheat. Why wouldn't I want to max out my stats when it doesn't prevent me from seeing new scenes?
The skills are an interesting idea, but it really needs some work beyond "would you like to see this scene?".
