Yay, I'll play all routes, of course. I mean I have my favorites, but I really want to see all of them too. Rei is my favorite character of them all so I bet I'll have fun playing all routes.
I'm pretty sure I've never been this excited about a game before (including even big titles like Dragon Age Inquisition or Mass Effect) - probably because I find the premise so unique. Ugh, I'm really trying to tone down my hype or I'll drive myself up the walls waiting.
