PC games? (each answer gets props!)

So I recently wanted to get anime themed PC games!

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

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

I'll give for 5 pujian per game anda daftar

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