How do you think the routes will work?
Do you think that the routes will only be split in the early game, and will then merge? Or that they'll merge later on, or perhaps never?
Do you think that the plot will be the same, mostly the same, or different depending on your route?
Will you fight the other houses in a war, depending on what path you choose?
And lastly, what about the other students? Do you think you will only get the students from your house, or that you'll recruit the other houses' students as well?
