Well VNs for me are never ending stories
Even after I finish, I still live with the characters in my mind
And I finally look up all the MADs, mashups etc on youtube and niconico xD
And since I have full soundtrack unlocked I download OST so I can listen to it outside of the game.
Well, what more to say, if the ending is good, it just inscribes into my heart and stays there forever.
I never skip ED song and I just enjoy it the last second, sometimes if the VN doesn't automatically transition into menu, I just stay there looking at the company logo or whatever the last screen is, thinking about how good it was
Often tiemes it transitions into menu and the menu is changed so I look at the new menu xD
Then I often replay good moments from memo saves I make throughout the game.
Don't know what more to say without mentioning specific VNs, but that would be for the specific VN topic including spoilers, not this one.
