PC games? (each answer gets props!)

So I recently wanted to get anime themed PC games!

I'd just like wewe to orodha as many as wewe know (they can be anything, romance/mystery/bloody/girly)
, but if wewe want props:

They MUST be translated into english
Please give a good description on each
and if there is an anime of them, let me know!

I'll give for 5 heshima per game wewe orodha

I already know and own kanon, air, and clannad!
Thanks very much!
