I would personally wish for a timer to keep progress of how much time I have spent on one vn or route, some vns have that feature while others don't but it would be really nice for moderns vn to add that feature.
Sachi is the only route I liked and which looked natural. And she is great as a person. Maybe too loud, but that's part of her charm. Lazy and illogical sometimes, but in the end she can overcome herself and pull herself up. That's so rarely happen in real life, and it really need even more efforts than it shown in VN. So I do not know how anyone could complain about this being stupid, you seems live in a paradise, if you never saw such problems. That was awesome route with great characters. Sadly cannot tell this about the rest...
