Starbound for #16 ("Starbound or Terraria?").

And for ideas for games that may be good to add:
The new Thief (You'd be best to get a key off of a trader, it'll be much cheaper since it came available with AMD graphics cards. You could get Thief, Hitman Absolution, and Sleeping Dogs for $15 total and then give away all three of these (or maybe keep Sleeping Dogs for yourself because that's like the best game ever)).
Wolf Among Us
Broken Age (Today's daily deal)
Left 4 Dead 2 (or Left 4 Dead combo pack that contains 1+2)
Mark of the Ninja (very fun indie sidescroller)
Borderlands GOTY (Haven't played it but BL2 is extremely fun)
Tomb Raider (Really fun if you haven't played it)
Mirror's Edge (Unique and awesome)
Deus Ex: HR (I've logged a lot of hours on this game)
Fortix
Darkness 2
Payday (1 and/or 2)
State of Decay

Contagion (it's cheap!!!)

Starbound

Gothic series.

nexuiz!

Starbound for 16! It is basically a more quest-oriented version of Terraria so.

Metal gear rising would be an interesting addition.

COD Ghosts or Batman Arkham Origins or pretty much anything free :D

CS:GO
