I highly recommended playing the original clannad game. The story line has more depth, detail and humor than what can be delivered to you in a film version. Plus, the moments where you must make choices; that interactivity connects you to the story line and brings life to the characters.
I've thought about making a story based animation game. Perhaps like 80% animated story plot decision making and 20% various-goal-oriented activities (an anything goes type of mini interactive game(s)) within the animated story game.
now i wonder if what i just wrote makes any sense to anyone...
That's an interesting concept. I feel like a LotV "choose your own adventure" would be a lot like the visual novel for School Days, where everybody is trying to kill each other and climb over the other's head, only to have everyone literally or figuratively fucked in the end. Good idea.
