PC games? (each answer gets props!)

So I recently wanted to get 아니메 themed PC games!

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

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

I'll give for 5 props per game 당신 list

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