PC games? (each answer gets props!)

So I recently wanted to get animé themed PC games!

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

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

I'll give for 5 hommages per game toi liste

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