Key Visual Novel

Have any of you read the visual novel's Kanon or Air? I'm just starting the animes (please no spoilers), but read up on their history that they stated out as eroge novels, how did they turn into epic shows?

I have yet to play their VN's

Kanon was originally a 12 episode series animated by Toei Animation. It was then reanimated by Kyoto Animation which has 20+ episodes. Toei's animation follows the VN closer than KyoAni's rendition does, however KyoAni's animation is superior to Toei's.

Air was animated by KyoAni.

While you're at it, watch Clannad and Clannad After Story, if you haven't already.

I just recently finished Clannad/~After Stories~, as well as Angel Beats! so good in fact, I bought both Air and Kanon without viewing an episode online to see if it's any good, just because it was done by Key. I'm starting Air and so far it looks like it's going to be a good one, as for Kanon (the KyoAni Version), I just got it today and will probably start it after Air.

yes i have watched kanon but air not yet
clannad and clannad after story was awesome
such a tear jerker anyway i havent finish the visual novel yet so ill try to read it up

I haven't watch AIR yet.
But for Kanon (by Kyoani) .. It's a good show nonetheless.
It's like in every episode you will got comedy and sad story at the same time .. there are a lot of emotional scenes that you will find touching.

Maybe Kanon is inferior to Clannad.
But it still 'worth to watch' anime, go for it.

Anything made by KEY will make you rip your heart out and then eat it while shedding tears of sadness. Because that's how awesome they are at making emotional scenes.
