yup i tried others' route but somehow they were overwhelmed by riho's so it wasn't as emotionally touching. Kanade's route good, but riho's the best. Rimu's, in my opinion, was written rather poorly.
I have just finished Riho's route a moment ago. I must say I've not been captivated...or perhaps, possessed...since a long while. The lingering feelings were so deep that I feel "let's just keep this moment a while longer.." I have enjoyed this very much!
