The Martian Investigations is a narrative-deduction game, which uses the same mechanics as Sherlock Holmes: Consulting Detective. In The Martian Investigations, you take the role of Detective Hayley Bendis, who has been sent to a mining colony on the surface of Mars in order to solve a series of grisly murders. You can get more information, here.
Litterateur is a word-building card-drafting game. You can think of it as Scrabble mixed with Sushi Go, but with an unusual victory mechanic. You can get the free Print-n-Play of Version 1, here.
Eccentric Exhibits is a free, 20-card trick-taking game for 2-players. Each player is a curator at a rival museum, attempting to win the best artifacts for their collection. You can get the free Print-n-Play here.
