5 or more LIs are too time consuming if you like all the LIs. So many play throughs and so many routes to update that the story never gets finished. BaDIK suffers from this.
Another really skillful thing taken over by computers. It is the same with playing the drums. I can play, but I can't keep time like a drum machine. Even if listeners can't hear it, I can.
I see a lot of RPGM games where I like the premise, but don't want to play the sprite running around finding scenes. Hero Part Fall or something like that comes to mind and I wish it would be made in Renpy.
