PC games? (each answer gets props!)

So I recently wanted to get Anime themed PC games!

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

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

I'll give for 5 Requisiten per game Du Liste

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