My favorite thing about people saying my ideas aren't good is executing them anyway and proving everyone wrong.That... really doesn't sound like a good idea.
LiL will be not only the longest visual novel ever made, but has the potential to be the longest fictional work of all time if it continues for several more years at this rate, which it will.
How can it last that long? Because it's not just one linear story. It's over 30 of them being developed simultaneously.
Every character will have a standalone game's worth of content by the end, because that is what they deserve.
I don't care about whether or not you or anyone else thinks that's a bad idea. I am going to do it anyway, and I am going to succeed. And anyone who gets bored is able to hop off the train whenever they want as there are plenty of other passengers lining up to buy tickets for the ride.
