Different Versions of Clannad?

[LostChikage]

Are there like different versions of Clannad? (Like Kanon) or is there only on Clannad?

If you mean different versions as in 'All-Ages, Original, Voiced' or 'PC/PS2/DC' there is only one version for Clannad and that is the clean non-voiced PC version. There may be upgrade patches for different numerical versions though, I'm not sure.

I believe there are some minor differences in the script in the second edition -- for example, in the first edition Ryou gives her birthday as Sep 14th, which is five days after her twin sister was born, and I gather they corrected that.
