PC games? (each answer gets props!)

So I recently wanted to get アニメ themed PC games!

I'd just like あなた to 一覧 as many as あなた know (they can be anything, romance/mystery/bloody/girly)
, but if あなた want props:

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

I'll give for 5 リスペクト per game あなた 一覧

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