Best games that can be completed in under ten hours?

So this isn't directly related to patientgaming but my hardware and personal tastes kind of filter me to playing games no newer than five years old.

I'm looking for some recommendations for games that can be completed within ten hours. I've realized recently that this is the sweet spot how much I enjoy playing a game before I get bored of it. I'm open to all types of games. Thanks in advance!
